Fabrication of tailored Ti6Al4V-based materials by conventional powder metallurgy for bone implant applications

ABSTRACT This works proposes a methodology for fabricating materials with specific characteristics mimicking human bones. A Ti64 alloy powder was used as the base material and it was mixed with Ag, Ta, TiN and salt particles to obtain different features. A hip-bone like component was fabricated, including a highly porous core of Ti64/25Ta/5Ag and a compact outer shell of Ti64/5Ag that is supposed to improve corrosion and osseointegration. Besides, a harder cover surface in Ti64/10TiN composite should increase the wear resistance. The green component was sintered at 1260°C in argon. Its Young’s modulus was close to the one of bones due to the added porosity, which also provided a permeability close to the one reported for trabecular bones. Tribocorrosion behaviour in simulated body fluid was improved by TiN addition. In conclusion, the proposed processing route was able to produce complex components fulfilling specific features required for human bone replacement.

Cold spray direct writing of flexible electrodes for enhanced performance triboelectric nanogenerators

Triboelectric nanogenerator (TENG) is an emerging energy harvesting device to effectively harness various mechanical energy sources. In TENG technology, polymers are of particular interest as tribo-negative materials owing to their unique properties (e.g., charge storage capability, impact resistance, flexibility, low cost, recyclability, etc.). Despite significant advances, one major challenge for TENG is to develop high-performance back electrodes that are conformably attached to the tribo-negative polymer substrates to fully exploit the potential of TENG in energy harvesting. To this end, the present study is aimed to employing direct “cold spray” particle deposition as just one-step fabrication method for high-performance electrodes on flexible polymers. In this regard, Tin (Sn) particles are directly written on the polymer (PET) surface by cold spraying to achieve conformal electrodes with high-adhesive strength and stable electrical conductivity. The resulting electrodes are thoroughly characterized in terms of microstructure, adhesion strength, and electrical performance. Arc-shaped TENG devices with both traditional aluminum (control) and cold-sprayed Sn electrodes are fabricated, followed by evaluating the TENGs' performance. Owing to the strong adhesion and micro-roughness (i.e., Ra = 4.865 μm) of the Sn electrodes, electricity generation performance was found to be improved by ≈2.4 folds as compared to the control TENG. The TENG with Sn electrode can generate an open-circuit output voltage of up to 243 V with a maximum output power of 130 mW/m2, thereby indicating the promising potential of the cold spray technique in TENG technology.

Synergistic Strengthening Mechanisms of Dual-Phase (TiN+AlN) Reinforced Aluminum Matrix Composites Prepared by Laser Powder Bed Fusion.

Dual-phase reinforcing approach provides a novel and efficient strategy for the fabrication of advanced aluminum matrix composites (AMCs). The devisable and desirable performance could be achieved by tuning dual-phase reinforcing system. However, it is still challenging to design a dual-phase reinforcing system with synergistic strengthening effect, especially for the laser powder bed fusion (LPBF) characterized by nonequilibrium metallurgical process. In this work, we designed and fabricated dual-phase (TiN+AlN) particles (20 wt.%) reinforced pure Al by LPBF. The TiN and AlN can form a metastable ternary Ti1-xAlxN solid solution in the whole range of composition, which is a promising reinforcing phase for AMCs. We observed novel microstructure in laser-fabricated composites under the action of dual-phase (TiN+AlN) ceramic particles and laser melting process. A gradient layer is formed on the surface of TiN particles. This interfacial structure can act as an anchor for ceramic particles in the Al matrix, which is beneficial to achieve a strong interface bonding and good load transfer. Besides this gradient layer, uniformly dispersed Ti1-xAlxN nanoparticles were observed to precipitate, which can effectively hinder dislocation movement and refine grains. Furthermore, the pure Al and TiN/Al, AlN/Al composites were fabricated to compare and reveal the contributions of dual-phase (TiN+AlN) reinforcements. The tensile strength of the (TiN+AlN)/Al composite reach ∼254 MPa, improved by ∼75% and ∼81% compared with those of the TiN/Al and the AlN/Al composites, respectively. This novel microstructure about gradient layer and precipitated nanoparticles contributes to the high strengthening efficiency of the (TiN+AlN)/Al composite.

Particles, Microstructures, and Impact Toughness of CGHAZ of Ca Deoxidation Shipbuilding Steel Plates with Different Nb Contents

Herein, the effects of the Nb content on the particles, microstructure evolution, and mechanical properties of base metal (BM) and high‐heat input coarse‐grained heat‐affected zone (CGHAZ) of shipbuilding steel plates with Ca deoxidation are studied. With increasing Nb content, the strength and microhardness of the BM increase without significant loss of impact toughness. However, in CGHAZ, the average grain size increases from 168 to 244 μm, and the brittle phase fraction increases from 0.33% to 11.76%. The high‐angled grain boundary (HAGB) density in microstructures reduces from 0.35 to 0.19 μm−1, and the average effective grain sizes increase from 10.97 to 12.48 μm. The particles in 40 Nb‐BM and 40 Nb‐CGHAZ are mainly cubic TiN particles. In 170 Nb, except for cubic particles, there are approximately ellipsoid particles with high value of Nb content, which tend to dissolve into matrix at the elevated temperature. With increasing Nb content, the average size of particles in CGHAZ increases from 18.33 to 32.29 nm, and the number density decreases from 13.44 to 10.35 μm−2. Therefore, the impact toughness of CGHAZ decreases from 197 to 96 J at −20 °C under the high‐heat input welding of 400 kJ cm−1.

Study of the Phase Composition, Structure and Mechanical Properties of Synthetic Composites Produced by High-Temperature Vacuum Sintering of SHS-Fabricated CrNi-TiN Powders

This work studies the phase composition, structure and mechanical properties of composite materials obtained by high-temperature vacuum sintering of SHS-fabricated CrNi–TiN powders synthesized in semi-industrial-scale production conditions. It was found that changes in the synthesis conditions have no effect on the phase composition and structure of the final products. Additionally, a small increase in the average size of ceramic TiN particles was observed. Compacted rectangular samples were obtained by high-temperature vacuum sintering of fine-ground CrNi–TiN SHS products. A minimum sintering temperature was found at which specimens with a density of 95% of the theoretical one could be obtained. The structure of sintered composites inherits the metal-matrix structure of a part of SHS products. It was shown that CrNi–TiN composite materials are superior to NiTi–TiB2 composites in terms of hardness as well as binding strength for three-point bending at temperatures up to 550 °C.

Microstructure evolution, mechanical properties, and strengthening mechanisms of heat-resistant Al-based composite reinforced by a combination of AlN and TiN particles

A novel heat-resistant Al matrix composite was fabricated, reinforced by a combination of nano-AlN and submicron TiN particles, i.e., (5TiN+6.4AlN)/Al composite, using the liquid–solid reaction method, and followed by an extrusion process. According to scanning electron microscopy and transmission electron microscopy results, AlN particles with an average size of 45 nm were mainly distributed along the intergranular grain and partially distributed in the grains, and TiN particles with an average size of 300 nm were uniformly distributed in the Al matrix. The novel composites exhibited excellent tensile strength at both room temperature (RT), especially at high temperature (350 °C, HT), reaching 400 and 195 MPa, respectively. The TiN particles were found to further generate the effect of dispersion strengthening, while the AlN particles were effective in stabilizing the grain boundaries and pinning dislocations at HT. The enhancement of grain boundary stability by the intergranular particles and dislocation pinning by the intragranular particles were the main strengthening mechanisms of the composites at 350 °C. Based on the critical roles of the dispersive reinforcement particles and theoretical calculations at RT, the Orowan strengthening of AlN plays a dominant role at RT. This work may provide new ideas for the development of high-strength heat-resistant Al matrix composites.

How the duty cycle affects wear and corrosion: A parametric study in the Ni–B–TiN composite coatings

TiN-reinforced Ni–B composite coatings were synthesized in the watts bath using pulse electrodeposition method at different duty cycles of 20%, 40%, 60%, and 80%. The surface morphology, phase structure, hardness, wear, and corrosion behavior of the coatings produced at different duty cycles were examined. The effect of the duty cycle on the microstructure of the composite coating was investigated using scanning electron microscopy (SEM) analysis. Depending on the duty cycle, a coating thickness of ∼69.7μm was obtained on the cathode surface. Crystallite size and lattice distortion of coatings were calculated with X-ray diffraction (XRD) data. The nano-indentation hardness results showed that the high nucleation rate at 40% duty cycle increased the coating hardness to 1170 HV. The wear test results indicated that the distribution of TiN particles in the coating content reduced the wear rate of the coating to 2.121 × 10−5mm3/Nm. Corrosion tests performed in 3.5 wt.% NaCl solutions were analyzed by Tafel curves and electrochemical impedance spectroscopy (EIS). Depending on the duty cycle/reinforcement particle distribution relationship, icorr and Ecorr values were measured as 2.27x10 −6 (A/cm 2) and -0.427 V, respectively.

Effect of interfacial structure on peel strength between Cu and AlN bonded with a Mg–Ti co-deposited film

Eliminating electrochemical migration of Ag is effective for improving the long-term reliability of power modules for high-voltage applications. In this work, a Cu plate was bonded onto an AlN substrate via Mg–Ti co-deposited films with three different compositions as Ag-free bonding materials between 800 and 950 °C for 0.5 h. The interfacial structures and the peel strength between the Cu and AlN were investigated by using the Surface And Interfacial Cutting Analysis System (SAICAS). Cu was bonded onto AlN through a TiN layer consisting of TiN particles and a Cu-containing grain boundary phase. All fractures at the Cu/AlN interface were observed to occur between the TiN layer and AlN after the SAICAS test. The peel strength at the Cu/AlN interface, which was independent of the thickness of the TiN layer, increased exponentially with increasing bonding temperature. Cu-containing phases, such as grain boundary phases and segregation phases between TiN particles and AlN, were present at the TiN layer/AlN interface. Mg and O were segregated at the interface, which had a high peel strength between the Cu-containing phase and AlN, while at the signal peak position of Mg, a plateau was observed in the Al concentration distribution between the Cu-containing phase and TiN particle. The peel strength of the Cu-containing phase/AlN interface, which increased as the O concentration in the Mg-containing segregation layer increased, dominated that of the TiN layer/AlN interface.

Boosting Thermal and Mechanical Properties: Achieving High-Safety Separator Chemically Bonded with Nano TiN Particles for High Performance Lithium-Ion Batteries.

Currently, the commercial separator (Celgard2500) of lithium-ion batteries (LIBs) suffers from poor electrolyte affinity, mechanical property and thermal stability, which seriously affect the electrochemical performances and safety of LIBs. Here, the composite separators named PVDF-HFP/TiN for high-safety LIBs are synthesized. The integration of PVDF-HFP and TiN forms porous structure with a uniform and rich organic framework. TiN significantly improves the adsorption between PVDF-HFP and electrolyte, causing a higher electrolyte absorption rate (192%). Meanwhile, XPS results further demonstrate the tight link between PVDF-HFP and TiN due to the existence of TiF bond in PVDF-HFP/TiN, resulting in a strong impediment for the puncture of lithium dendrites as a result of the improved mechanical strengths. And PVDF-HFP/TiN can effectively suppress the growth of lithium dendrites by means of uniform lithium flux. In addition, the excellent heat resistance of TiN improves the thermal stability of PVDF-HFP/TiN. As a result, the LiFePO4 ||Li cells assembled PVDF-HFP/TiN-12 exhibit excellent specific capacity, rate performance, and capacity retention rate. Even the high specific capacity of 153 mAh g-1 can be obtained at the high temperature of 80°C. Meaningfully, a reliable modification strategy for the preparation of separators with high safety and electrochemical performance in LIBs is provided.

Nanomechanical and Electrochemical Corrosion Testing of Nanocomposite Coating Obtained on AZ31 via Plasma Electrolytic Oxidation Containing TiN and SiC Nanoparticles

Lightweight magnesium alloys offer excellent benefits over Al alloys due to their high specific strength and damping properties, but they are more prone to galvanic corrosion. Plasma electrolytic oxidation (PEO) coatings reinforced by nanoparticles have been shown to improve corrosion resistance and possess better mechanical properties. A lot of research has been published that focuses on the effect of nanoparticle concentration in the PEO electrolyte solution, and the type of nanoparticle, on the properties obtained. The aim of paper is to study the effect of processing time on the nanoparticle-reinforced PEO coating on AZ31 magnesium alloy. TiN and SiC nanoparticles were produced using plasma chemical synthesis and added to KOH-based electrolyte to develop PEO coatings. The concentration of nanoparticles was kept constant at 0.5 g/L and the treatment time was varied as follows: 1, 2, 3, 5, and 10 min. The coatings were tested for their microstructure, phase, chemical makeup, nano-mechanical properties, and corrosion resistance. Nanoparticles were found to be clustered in the coating and spread unevenly but led to a decrease in the size and number of pores on the PEO coating surface. The corrosion resistance and nano-mechanical properties of the coating improved with treatment time. The hardness and contact modulus of coatings with TiN particles were 26.7 and 25.2% greater than those with SiC particles. Addition of TiN nanoparticles resulted in improved corrosion resistance of the PEO coatings when the processing time was 5 or 10 min. The lowest corrosion rate of 6.3 × 10−5 mm/yr was obtained for TiN-added PEO coating processed for 10 min.

Experimental characterization of tool wear morphology in milling of Al520-MMC reinforced with SiC particles and additive elements Bi and Sn

Combining aluminium as a soft, lightweight, and low-strength material with reinforcing elements may lead to fabricating materials with excellent abrasion resistance and a high strength-to-weight ratio. However, these fabricated materials are classified as difficult to cut materials due to elevated tool wear size. According to the literature, limited studies were reported on the effects of various reinforcing elements on the machinability of Al520-MMC, mainly tool wear morphology and size. Therefore, in the course of this study, Al520-MMCs were fabricated with various reinforcing elements, such as silicon carbide (SiC), bismuth (Bi), and tin (Sn) particles. No similar work was found in this regard. Accordingly, as an originality of this work, besides fabricating new MMcs, the experimental characterization of tool wear morphology was conducted when milling Al520-MMCs with various reinforcing elements. Despite the reinforcing elements used, higher tool flank wear was observed under dry machining. Furthermore, knowing that Al520-MMC is a soft metal, the built-up edge (BUE) was observed under all lubrication modes and cutting speeds. Additionally, abrasion was found in all cutting conditions used. Therefore, it could be stated that the reinforcing elements and cutting speed had the most significant effects, and the lubrication mode had minimal impact on the wear size. Compared with the recorded values of tool flank wear in machining Al520 + 10% SiC, the flank wear was reduced by around 50% when Bi and Sn were used in the matrix structure. In other words, using bismuth (Bi), and tin (Sn) particles may lead to better tool life.

In-situ non-destructive removal of tin particles by low-energy plasma for imitation of EUV optical mirrors self-cleaning

In this study, the feasibility was explored of realizing in-situ and non-destructive self-cleaning of the multilayers mirror (MLM) by utilizing hydrogen plasma at low input power (<10 W). The hydrogen plasma generated by the electrode at low power was comprehensively diagnosed using the Langmuir probe and the retarding field ion energy analyzer (RFEA). Meanwhile, the ion concentration ratios and atomic density in hydrogen plasma were calculated by constructing a zero-dimensional plasma chemical model. These experimental results show that the plasma distribution at 1 W is more uniform than that at 10 W, and the peak ion energy at 1 W is lower than 22 eV. Cleaning rates of 0.3–0.75 nm min−1 are achieved to remove discontinuous tin particles at different powers. According to the experiment and calculation results, the chemical etching of ions (breaking the Sn–Sn bond) occurred at 1 W. The etching yield is 0.23–0.87 Sn/ion for 10–40 eV. The analysis of surface morphology and cross-sectional morphology shows that the removal of tin particles is realized by top-down cleaning with hydrogen plasma at low power. This study is of great significance for understanding the detailed mechanism of MLM self-discharge cleaning tin pollutants at low power. It has made a comprehensive calculation and diagnosis of plasma parameters.

Effect of Normalizing on Impact and Corrosion Resistance of Low-temperature Service Seamless Steel Pipe

The seamless line pipe, which has fine low temperature impact properties for Low-temperature Service and good H2S corrosion resistance, was investigated through chemical composition designing, optimizing smelting-rolling processes, and heat treatment processes following ASTM A333 standard. The influence of normalizing on the impact property and corrosion resistance was studied by optical microscope, scanning electron microscope, transmission electron microscope, mechanical test and corrosion test. It is demonstrated that the low temperature mechanical properties and anti-H2S corrosion properties of hot-rolled trial-pipe and normalized trial-pipe meet ASTM A333 standard. The microstructure of hot-rolled trial-pipe is pearlite and ferrite, and the grain distribution is uniform and grain size is fine. The dominated precipitates phase are TiN particles in hot-rolled trial-pipe. Ductile to brittle transition temperature is determined at -60 °C. The grain refinement is achieved after normalized and the main precipitates are TiN particles together with a few VN particles. Ductile tobrittle transition temperature was further lowered, at - 80 °C. The corrosion behavior of the material was examined by hydrogen induced cracking (HIC) corrosion test, sulfide stress corrosion (SSC) test and polarization test at various polarization scanning rates. It is observed that the anti-HIC corrosion performance and SSC corrosion resistance are similar for both hot-rolled and normalized pipes, but the performance of electrochemical corrosion of normalized pipe is better than hot-rolled pipe, which indicates that the normalized pipe is more suitable for demanding corrosive environments.

Synthesis and sintering properties of silica-coated titanium nitride particles

Herein, we synthesized silica-coated titanium nitride (TiN/SiO2) particles via a sol–gel method and evaluated the hardness of the sintered bodies fabricated using the as-fabricated TiN/SiO2 particles. Commercially available micron-sized TiN particles were dispersed in a water–ethanol solution at 35 °C and then coated with SiO2 using a sol–gel method, tetraethyl orthosilicate (TEOS), and base catalysts. TiN/SiO2 particles with small specific surface areas owing to the presence of few micropores in their structure were obtained using NaOH as the base catalyst. The Vickers hardnesses of TiN, a mixture of TiN and SiO2 (TiN–SiO2), TiN/SiO2 fabricated using an ammonia solution as the base catalyst (TiN/SiO2A), and TiN/SiO2 fabricated using NaOH as the base catalyst (TiN/SiO2S) increased as follows: TiN (6.35 × 102 Hv) < TiN–SiO2 (1.01 × 103 Hv) < TiN/SiO2A (1.11 × 103 Hv) < TiN/SiO2S (1.15 × 103 Hv). In summary, the SiO2 shell served as a sintering aid, and the NaOH catalyst densified the sintered body and improved its hardness.

Microstructures and Mechanical Properties of Alumina and/or Yttrium Oxides Strengthened 9Cr Steel Fabricated by Vacuum Casting

The oxides with Al2O3‐containing and/or Y‐containing are introduced into 9Cr ferritic/martensitic steel fabricated by vacuum casting to modify its microstructures and improve its mechanical properties. The results show that the micron nonmetallic particles are refined, and the number of submicron particles is increased after the introduction of Al2O3‐containing oxides, while the number of submicron particles is decreased when both Al2O3‐and Y‐containing oxides are introduced. The average grain size, the width of martensite, and the M23C6 phases in the tempered steel are optimized when the Al2O3‐containing oxides are introduced. However, with the further introduction of Y‐containing oxides, these tempered microstructures do not change much, except for the precipitation of the δ‐Fe phase. Due to the grain refinement and second‐phase particle strengthening after the introduction of Al2O3‐containing particles, the tensile strength is improved not only at room temperature but also at 550 °C, but the impact energy drops significantly, which is caused by a large number of TiN particles promoted by Al2O3 particles through heterogeneous nucleation. At the same time, the further introduction of Y‐containing oxides reduces the tensile strength and increases the elongation at room temperature, which is attributed to the precipitation of soft δ‐Fe promoted by the addition of Y.

A High Voltage Aqueous Zinc-Vanadium Redox Flow Battery with Bimodal Tin and Copper Clusters by a Continuous-Flow Electrometallic Synthesis.

Aqueous zinc-based redox flow batteries are promising large-scale energy storage applications due to their low cost, high safety, and environmental friendliness. However, the zinc dendritic growth has depressed the cycle performance, stability, and efficiency, hindering the commercialization of the zinc-based redox flow batteries. We fabricate the carbon felt modified with bimodal sized tin and copper clusters (SCCF) with the electrometallic synthesis in a continuous-flow cell. The SCCF electrode provides a larger zinc nucleation area and lower overpotential than pristine carbon felt, which is ascribed to the well-controlled interfacial interaction of bimodal tin and copper particle clusters by suppressing unwanted alloy formation. The zinc symmetric flow battery and the zinc-based hybrid redox flow battery show the improved zinc plating and stripping efficiency. The SCCF electrode exhibits 75% improved cycling stability compared to the pristine carbon felt electrode in the zinc symmetric flow battery. Notably, the high-voltage aqueous zinc-vanadium redox flow battery demonstrates a high average cell voltage of 2.31 V at 40 mA cm-2, showing a Coulombic efficiency of 99.9% and an energy efficiency of 87.6% for 100 cycles. We introduce a facile strategy to suppress the zinc dendritic growth, enhancing the performance of the zinc-based redox flow batteries.

Melt pool signatures of TiN nanoparticle dry-coated Co25Cr25Fe25Ni25 metal powder in laser-powder-bed-fusion

Metal powders in laser-powder-bed-fusion (L-PBF) often exhibit cohesive flow resulting from interparticle adhesion. Nanoparticle dry-coating can improve powder flowability and promote powder layer densification. A Co25Cr25Fe25Ni25 metal powder (20–90 µm) is dry-coated with TiN particles with a diameter of 16 nm at low concentrations of up to 69 ppm. The dynamic angle of repose decreased and bulk powder density increased compared to the uncoated state from 49 ° and 4.67 g/cm3 to 29 ° and 4.81 g/cm3 with dry-coating of TiN, respectively. UV/Vis spectroscopy showed negligible alterations by TiN additions on the powder light absorption. The powder modifications strongly affected their corresponding processability in L-PBF and reduced the melt pool signatures of the in situ detected confocal single-color pyrometer signal as well as ex situ measured melt pool depth and width. With increasing flowability, a significant decrease in thermal emission and melt pool size was observed. The results demonstrate the impact of powder flowability and bulk powder density on the quality of L-PBF parts when particle interactions are actively modified.

In Situ Synthesis of Hierarchical Flower-like Sn/SnO2 Heterogeneous Structure for Ethanol GAS Detection.

In this study, morphogenetic-based Sn/SnO2 graded-structure composites were created by synthesizing two-dimensional SnO sheets using a hydrothermal technique, self-assembling into flower-like structures with an average petal width of roughly 3 um. The morphology and structure of the as-synthesized samples were characterized by utilizing SEM, XRD, XPS, etc. The gas-sensing characteristics of gas sensors based on the flower-like Sn/SnO2 were thoroughly researched. The sensor displayed exceptional selectivity, a rapid response time of 4 s, and an ultrahigh response at 250 °C (Ra/Rg = 17.46). The excellent and enhanced ethanol-gas-sensing properties were mainly owing to the three-dimensional structure and the rise in the Schottky barrier caused by the in situ production of tin particles.

β grain refinement during solidification of Ti-6Al-4V in Wire-Arc Additive Manufacturing (WAAM)

Constructing titanium aerospace parts by near-net-shape processing has the potential to greatly reduce cost and lead time, one method for this is Wire-Arc Additive Manufacturing (WAAM). Conventional WAAM processing with the most common Ti alloy, Ti-6Al-4V, results in solidification by epitaxial growth from previously deposited layers and a structure dominated by columnar β grains which are heavily <001> fibre textured and cm’s in scale. In order to prevent these large grains from forming, while maintaining deposition parameters, the solidification conditions were modified by the additions of particles to the melt; either using inoculant, TiN particles, or the solutal growth restrictor, Y, also added as elemental powder that dissolved in the melt. The powder particles were added by adhering them to the deposited tracks to avoid the costs of manufacturing new wires. With TiN inoculants the morphology of β grains was completely modified to equiaxed grains averaging 300 μm in diameter. Y additions narrowed the columnar grains from 1-2mm to 100-300 μm. Y also induced a change to equiaxed grains, late in solidification, in the region which was remelted by subsequent deposition. However, Yttria particles were found to have formed interdendritically with an interconnected skeletal morphology. High-resolution EBSD analysis showed both TiN and yttria particles exhibit specific orientation relationships with the solidified β grains, which were confirmed experimentally.

Microstructure development, mechanical properties and underlying mechanism of micro-TiN-reinforced AlSi10Mg composites fabricated by selective laser melting

In this study, aluminum matrix composites reinforced with micro-TiN were fabricated using selective laser melting (SLM) technique. The study investigates the effects of TiN content on densification, microstructure evolution, crystal textures, and mechanical properties. The results show that the relative density of composite samples containing 0?3 wt. % TiN exceeds 98%. However, further increase in TiN content leads to a decrease in relative density. The TiN particles are uniformly distributed and wetted by the AlSi10Mg matrix, forming a graded interfacial layer. The TiN particles refine the matrix grains and significantly reduce the prevalence (001) texture by promoting a heterogeneous nucleation process. In comparison to the AlSi10Mg alloy, the TiN/AlSi10Mg composite exhibits improved microhardness, tensile strength, and wear resistance. The exceptional mechanical properties of the Al matrix composites are attributed to the dispersion strengthening of the TiN particles and the fine-grain strengthening of the matrix. The optimal TiN content is found to be 3 wt. %, resulting in excellent mechanical performance of the fabricated samples (132.4?4.1 HV for hardness and 379.7?4.6 MPa for tensile strength) with a low friction coefficient of 0.49.
