Production of (B4C+FeTi) reinforced and Fe based composites by mechanical alloying

Abstract In this study, the microstructure and mechanical performance of Fe-based composites reinforced by FeTi+B4C at various ratios were determined. The study was based on the production of Fe based nano carbide and boride (B4C, Fe2B, Fe7C3, TiB2) reinforced composites. Mechanical alloying technique was chosen to reduce the reinforcement material to nano size and distribute it homogeneously. Sintering temperature was used as 1,100 °C and sintering time as 2 h. The reionforcement “FeTi+B4C” ratio was raised up to 15 wt.%. The microstructure and phases of the composite samples were descrived by scanning electron microscopy, energy dispersive spectroscopy, X-RD analysis and hardness. The concentration of voids and the stiffness changes of the samples were determined. The size of TiC and TiB2 particles reduced significantly with the rise in B4C ratio. Since the hardness of TiB2 was less than that of the B4C matrix, the hardness reduced with increasing TiB2 ratio.

Role of Mo and Zr Additions in Enhancing the Behavior of New Ti–Mo Alloys for Implant Materials

AbstractThe utilization of Ti–Mo alloys in biomedical applications has gained attention for use in biomedical applications owing to their non-toxicity, reasonable cost, and favorable properties. In the present study, Ti–12Mo–6Zr and Ti–15Mo–6Zr alloys were prepared using elemental blend and mechanical alloying techniques. The effect of alloying elements Mo and Zr of Ti–Mo alloy, as well as the effect of fabrication techniques of Ti–Mo–Zr trinary alloys, were investigated. Thermodynamic calculations supported by CALPHAD analysis revealed that the addition of Zr increases lattice distortion, which contributes to enhancing the strength. Conversely, adding Mo decreases the enthalpy, facilitating improved mixing and solid solution formation. The as-sintered samples were characterized by X-ray diffraction, optical microscope, and scanning electron microscopy, and their microhardness, compressive, and corrosion behavior were investigated. Among all the investigated alloys, Ti–15Mo–6Zr alloy prepared by the mechanical alloying technique, milled for six hours at 300 rpm, compacted at 600 MPa, and sintered at 1250 ℃, shows good comprehensive mechanical properties with a preferable compressive strength (− 1710 MPa) and hardness (396 HV5), as well as the lowest wear rate (0.69%) and corrosion rate (0.557 × 10–3 mm/year). This can be related to the solid solution strengthening and relative density, together with dispersion and precipitation strengthening of the α phase. Remarkably, the combination of high mechanical and corrosion properties can be achieved by tailoring the content of the α phase, controlling the density, and providing new fabricating techniques for β Ti alloys.

Cu-Al-Ni Nanocrystalline Compacts Obtained by Spark Plasma Sintering of Mechanically Alloyed Powders.

The aim of this work is to obtain Cu-13.5Al-4Ni alloy for use as shape memory alloy by Spark Plasma Sintering (SPS) of mechanically alloyed powder. The study investigates the structural and microstructural changes in terms of crystal parameters, crystallite sizes, and phases evolution during mechanical alloying and spark plasma sintering of Cu-13.5Al-4Ni powders. We obtained alloyed powders with a structure composed of α(Cu), AlNi intermetallic compound and small amounts of elemental Al through the mechanical alloying technique. After spark plasma sintering at 900 °C, the microstructure consists of an AlNi compound distributed at the edge of α(Cu) grains. The crystallite sizes of both, α(Cu) and AlNi are in nanoscale order after 16 h of milling (9 and 6.5 nm respectively). After sintering at 900 °C (in Ar atmosphere, without holding time), the crystallite sizes increase to 46 nm for α(Cu) and to 40 nm for AlNi compound. Also, the Cu-13.5Al-4Ni compacts achieve a final density after sintering at 900 °C of around 80% from the theoretical density.

Production of high entropy (FeNiMnCrV)3O4 oxide by mechanical alloying process and electrochemical performance analysis for Li-ion cells

In this study, a high entropy oxide material was fabricated from its alloy using mechanical alloying technique in the form of (FeNiMnCrV)3O4 with a symmetry of Fd-3m, and their structural properties were investigated by XRD, SEM-EDS dot mapping, and XPS analyses. The EDS analysis results of oxide and alloy show that Fe, Ni, Mn, Cr, and V have similar ratios for both samples. The elemental ratios were also measured by ICP-MS and the results support the EDS and XPS data. The alloy and oxide powders were used for the production of the anode materials for the half-cell configuration of the battery. The CV analysis of both cells showed that they have similar characteristic redox reactions and the main difference between the two electrodes is the current density values in the peaks. The initial capacity value of the (FeNiMnCrV)3O4 for 10 mA/g was found as 1070 mAh/g for the first cycle which is promising results as an anode material for Li-ion cells.

An assessment of the mechanically alloyed equiatomic FeCoNiMnSi high entropy amorphous alloy for non-isothermal crystallization kinetics and magnetocaloric refrigeration application

We studied an equiatomic FeCoNiMnSi high entropy amorphous alloy successfully processed via mechanical alloying technique. The structural, magnetic, and magnetocaloric characteristics of the resulting materials were examined using X-ray diffraction, field emission scanning electron microscopy, high-resolution transmission electron microscopy, and a vibrating sample magnetometer. The structural analysis showed a prominent amorphous phase formation as the milling time increases from t = 0–35h of mechanical alloying. The differential scanning calorimetry was employed to investigate the non-isothermal crystallization kinetics of the 35-h milled sample. The results revealed that the milled powder consists of a single exothermic peak with its apparent activation energy (Eg, Ex, Ep) being determined using the Kissinger, Ozawa, and Augis-Bennett equations. The findings exhibit Ex > Ep > Eg, representing that nucleation is more complicated than the growth mechanism during the crystallization process. Meanwhile, under non-isothermal conditions, the Kissinger-Akahira-Sunose, Friedman, and Flynn-Wall-Ozawa models were calculated using the local activation energies that agree with the apparent activation energy. Furthermore, the Johson-Mehl-Avrami-Kolmogorov exponent (n) and Avrami-Ozawa combined [F(T)] models exhibit high-dimensional nucleation and growth with an increasing nucleation rate enabled by lowering the local activation energies as a function of degree of conversion with respect to temperature. In magnetic measurements, a feasible mathematical model was proposed as a novel strategy for predicting the value of saturation magnetization as a milling time function. The model has an exceptional predictive capability, confirmed by fitting other research outcomes. Finally, the proposed system also delivers the best magnetocaloric properties with a maximum magnetic entropy change of 3.70 Jkg−1 K−1 at 150 K curie temperature and a refrigeration capacity of 252.86 J/kg with 1000 Oe applied magnetic field.

Microstructure, thermal and radiation shielding properties of aluminium‐silicon‐boron alloy prepared by mechanical alloying

AbstractThis study focused on developing microstructural, thermal, and radiation shielding changes in Al50Si25B25 powders using mechanical alloying techniques. Based on the x‐ray powder diffraction data, the crystallite size and microstrain of the 100‐hours milled powder were calculated as 0.25 nm and 50.33 %, respectively. The solubility of silicon in the α‐aluminium matrix increased with longer mechanical alloying duration. Transmission electron microscope analyses further showed that the alloy particulates had an average size of 3 μm and an average grain size of 0.226 nm. The radiation shielding properties of the Al50Si25B25 powders indicated that the Linear Attenuation Coefficient value increased from 0.0554±0.1689 cm−1 to 1.0632±0.2425 cm−1 with an increase in the thickness of the Al50Si25B25 alloy. This work successfully demonstrated the potential of mechanical alloying techniques to enhance the microstructural and thermal properties of Al50Si25B25 powders. It highlighted their effectiveness in providing radiation shielding capabilities when varying the thickness of the alloy.

Microstructural evolution of CrCuFeNiZn nanocrystalline high entropy alloy prepared by mechanical alloying

High Entropy Alloys (HEAs) have become the most researched structural materials in the scientific community during the last decade due to their attributes like excellent strength and wear resistance. In this research, CrCuFeNiZn HEA was prepared using mechanical alloying technique. Further, X-ray diffraction (XRD) and Scanning electron microscope (SEM) analysis of prepared HEA were carried out at various milling time intervals (10 min, 5 h, 10 h, 15 h, 20 h, and 25 h) to determine solid solution formation. Results manifest that CrCuFeNiZn HEA exhibited BCC + FCC (dual phase) structure after 25 h of milling. Moreover, the crystallite size as measured from the XRD analysis for the 25 h milled powder was found to be 32.8 nm and lattice strain at the end of milling is calculated to be 0.428%. SEM-EDS analysis further confirms the homogeneous distribution of the constituting elements in the as-fabricated alloy aggregate.

Effect of sintering temperature on microstructure and mechanical properties of MoNbVTa0.5Cr high-entropy alloys fabricated by powder metallurgy method

To address the challenges posed by the high density and low plasticity at room temperature of traditional refractory high entropy alloys (RHEAs), the MoNbVTa0.5Cr RHEA was synthesized through a combination of mechanical alloying (MA) and spark plasma sintering (SPS) techniques. The effects of different sintering temperatures on the microstructure and mechanical properties of the alloy were systematically studied. The MoNbVTa0.5Cr RHEA milled up to 60 h was found to have a metastable dual-phase containing a major BCC (a = 3.1474 Å) and Nb-Ta (a = 3.3058 Å) phase. The sintered MoNbVTa0.5Cr RHEA was composed of BCC phase and a small amount of Ta2VO6 at different sintering temperatures. There were a lot of edge dislocations in the BCC matrix near the BCC/Ta2VO6 interface. With the increase of sintering temperature, the grain size of sintered MoNbVTa0.5Cr RHEA gradually increased, while the mechanical properties gradually decreased with the increase of sintering temperature. When the sintering temperature was 1500 °C, the grain size of the alloy was 2.33 μm, the yield strength was 2783 MPa, the compressive strength was 3346 MPa, and the fracture strain was 20.45 %, showing the best comprehensive properties. And the density of MoNbVTa0.5Cr RHEA was 9.11 g·cm−3 and 26 % lower than that of WNbMoTaV RHEA. The specific yield strength of MoNbVTa0.5Cr RHEA prepared in this research was 295.28 kPa·m3·kg−1, which was superior to most RHEAs reported so far. This sintered MoNbVTa0.5Cr RHEA showed an excellent room temperature compression performance, which can be attributed to the co-existence of BCC phase along with the minor Ta2VO6 phases. The high yield strength of MoNbVTa0.5Cr RHEA was mainly attributed to the substitutional solid solution strengthening of metal atoms, the interstitial solid solution strengthening of O atoms and the grain boundary strengthening of ultrafine grains, with contributions to yield strength of 41 %, 28 %, and 24 %, respectively.

Fabrication and characterization of in-situ Ti(C, N) – CoCrFeNi cermets via mechanical alloying and spark plasma sintering

Ti(C, N) cermets were prepared by adding CoCrFeNiTi to g-C3N4 and using mechanical alloying and spark plasma sintering techniques. The evolution of microstructure and the systematic analysis of the influence of different binder content on mechanical properties were investigated. This result demonstrates that with an increase in binder content, the grain size of Ti(C, N) in the cermets decreases, and the formation of spheroidal small grains becomes more prominent while the occurrence of large grains decreases. Additionally, the relative density and hardness of Ti(C, N) metal ceramics have slightly decreased. The fracture toughness of Ti(C, N)/HEA cermet is codetermined by the intrinsic sintering property and deformability of HEA binders. The Ti(C, N) cermets (CH3) exhibits excellently bending strength and fracture toughness，which are 1941 MPa and 11.2 MPa m1/2 respectively. The study aims to enhance the mechanical properties and toughness of Ti(C, N) and proposes a novel approach for the synthesis of Ti(C, N) cermet.

Microstructure and mechanical properties of Ti-Nb alloys: comparing conventional powder metallurgy, mechanical alloying, and high power impulse magnetron sputtering processes for supporting materials screening

At the interface of thin film development and powder metallurgy technologies, this study aims to characterise the mechanical properties, lattice constants and phase formation of Ti-Nb alloys (8–30 at.%) produced by different manufacturing methods, including conventional powder metallurgy (PM), mechanical alloying (MA) and high power impulse magnetron sputtering (HiPIMS). A central aspect of this research was to investigate the different energy states achievable by each synthesis method. The findings revealed that as the Nb content increased, both the hardness and Young’s modulus of the PM samples decreased (from 4 to 1.5 and 125 to 85 GPa, respectively). For the MA alloys, the hardness and Young’s modulus varied between 3.2 and 3.9 and 100 to 116 GPa, respectively, with the lowest values recorded for 20% Nb (3.2 and 96 GPa). The Young’s modulus of the HiPIMS thin film samples did not follow a specific trend and varied between 110 and 138 GPa. However, an increase in hardness (from 3.6 to 4.8 GPa) coincided with an increase in the β2 phase contribution for films with the same chemical composition (23 at.% of Nb). This study highlights the potential of using HiPIMS gradient films for high throughput analysis for PM and MA techniques. This discovery is important as it provides a way to reduce the development time for complex alloy systems in biomaterials as well as other areas of materials engineering.Graphical abstract

Investigating the valence balance of adding Nano SiC and MWCNTs on the improvement properties of copper composite using mechanical alloying and SPS techniques

This study presents a comprehensive investigation of copper-based nanocomposites reinforced with silicon carbide (SiC) nanoparticles and multi-walled carbon nanotubes (MWCNTs). The manufacturing procedure involved powder metallurgy techniques followed by spark plasma sintering (SPS). Microstructural analysis revealed a notable reduction in particle size (from 23.72 μm to 18.31 μm) and crystallite size (from 104.32 nm to 87.36 nm) with the addition of reinforcements. The bulk microstructure exhibited a reduction in grain size by approximately 13.1 %. XRD analysis confirmed the absence of new phases. Evaluation of SPS parameters demonstrated varying density and porosity, with the highest relative density of 99.96 % observed in pure copper composites. Hardness measurements indicated that surface hardness surpassed cross-sectional values, with the lowest recorded value being 64.79 HV for composite Cu-5%SiC-1%MWCNTs (S4). Wear rate analysis revealed an increase, with pure copper composites exhibiting a wear rate of 1.78 × 10^-4 mm3/m, while composite S4 displayed a rate of 3.25 × 10^-4 mm3/m under a load of 5 N. Coefficient of Friction (COF) exhibited significant fluctuations, influenced by the applied load and composite composition. Thermal conductivity decreased with higher SiC and MWCNT content, with sample S1 exhibiting the highest thermal conductivity among reinforced composites. Electrical conductivity trends were influenced by the type and concentration of reinforcing particles, resulting in an increase of approximately six times in composite S4 compared to the pure sample.

The present study deals with the fabrication of a novel AlCoMoFeNi high-entropy (HEA) alloy using mechanical alloying techniques. The developed HEA was characterized by X-ray diffraction, differential scanning calorimetry (DSC), scanning electron microscopy (SEM) equipped with energy dispersive x-ray spectroscopy (EDX), and transmission electron microscopy (TEM). The crystallite size of the high-entropy alloy solid solution was determined to be 20 ± 1 nm, with a lattice strain of 0.467 ± 0.03 % and a lattice parameter of 3.98 ± 0.08 Å. A number of characteristics, including melting point, mixing enthalpy change, mixing entropy change, atomic size difference, electronegativity difference, and valence electron concentration, were computed in order to ascertain the conditions regulating the formation of high-entropy alloys. A HEA with BCC and FCC solid solution was obtained after mechanical alloying, which was confirmed by experimental findings as well as thermodynamic calculations.

A powdered mixture of samarium and pure metallic cobalt (Co) precursors was subjected to 24 h of milling to achieve the intended sample. The phase transformations induced by high-energy milling were investigated through ex situ X-Ray Diffraction (XRD) measurements and analyzed using the Rietveld method. Some properties of SmCoO3 were examined using techniques such as Differential Scanning Calorimetry (DSC), heat treatment, XRF (X-Ray Fluorescence), and UVVis absorbance. These comprehensive characterizations provide valuable insights into the synthesis and properties of nanostructured SmCoO3 perovskite, facilitating its potential applications in various fields.

Synergistic strengthening mechanism and microstructural evolution of Al-Zn-Mg-Cu/ Al2O3/Y2O3 hybrid nanocomposite via mechanical alloying and hot pressing

Mechanical alloying (MA) and hot pressing (HP) were utilized to fabricate a hard ceramic dispersion (Y2O3 and Al2O3) in the Al-Zn-Mg-Cu alloy. Fracturing and severe plastic deformation phenomena during MA significantly reduced the powder particles to nanosize, and peak broadening was observed, along with a particle change from a flake shape to a spherical one. For the 20 h milled consolidated sample, the hybrid-reinforced composite sample exhibits higher Vickers microhardness, nanoindentation, and compressive strength compared to the blended samples at 0 h due to grain refinements and homogeneous dispersion of reinforcements. A comprehensive analysis of various strengthening mechanisms for the obtained compressive strength was quantitatively determined, and the results indicate that precipitate and dispersoid strengthening mechanisms were the principal ones compared to others (grain size, solid solution, and dislocation strengthening mechanisms). These findings mark the beginning of hybrid composite development through the MA and HP techniques.

Synthesis of Nickel-Based Medical Alloys via Mechanochemical Processing and Powder Metallurgy Techniques

In this study, medical nickel alloys suitable for dental applications were synthesised by a combination of force chemical synthesis and powder metallurgy. Titanium and base powders were used, processed in a hydrogen atmosphere to obtain sub-micron particle sizes and homogeneously mixed by mechanical alloying techniques to optimise sintering and compaction properties. This method ensures perfect consistency of particle composition and morphology, essential for the subsequent sintering process, which densifies the material to a relative density of 98.96% while maintaining the precise shape and weight specifications required. Manganese, boron and cerium are added in moderate amounts to enhance bond strength with porcelain veneers without sacrificing corrosion resistance or causing discolouration. Boron content is controlled below 0.1 weight percent to reduce brittleness, and silicon is adjusted to maintain mechanical strength. The alloy's coefficient of thermal expansion is optimised and determined by dilatometry techniques to ensure compatibility with porcelain and compliance with industry standards for nickel-based dental alloys. Tested mechanical properties including yield strength, tensile strength and Vickers hardness showed robustness and resistance that surpassed most nickel-based alloys and competed with cobalt-based alternatives. The study concluded that the advanced synthesis technology used to produce the nickelcontaining medical alloy has improved mechanical, thermal and aesthetic properties, making it ideal for the manufacture of dental prostheses that require high precision.

Glass-Forming Ability and Magnetic Properties of Al82Fe16Ce2 and Al82Fe14Mn2Ce2 Alloys Prepared by Mechanical Alloying

Al82Fe16Ce2 and Al82Fe14Mn2Ce2 amorphous alloys were successfully synthesized by the mechanical alloying technique. The microstructural evolution of the milled powders was thoroughly investigated employing X-ray diffraction (XRD) and scanning electron microscopy (SEM). Additionally, their magnetic properties were quantitatively evaluated by a vibrating sample magnetometer (VSM). A full amorphous structure was obtained for both alloys after milling for 40 h. During the initial milling stage, extending from 5 to 20 h, an fcc solid solution phase was formed, coexisting with the residual Al phase. The partial substitution of 2 atomic percent (at.%) Mn for Fe in Al82Fe16Ce2 did not affect the alloy’s glass-forming ability. The amorphous Al82Fe16Ce2 and Al82Fe14Mn2Ce2 powders exhibited a nearly spherical shape, with diameters ranging from 1 to 3 µm and to 10 µm, respectively. Additionally, both the Al82Fe16Ce2 and Al82Fe14Mn2Ce2 alloys demonstrated characteristics of hard magnetism.

Physical, mechanical, and corrosion properties of Ti–12Mo and Ti–15Mo alloys fabricated by elemental blend and mechanical alloying techniques

Ti–Mo alloys have received increased attention and concern in several applications, especially in biomedical, because of their appropriate properties, non-toxicity, and reasonable cost. This work investigated the different Mo powder content (12 and 15 wt%) fabricated by elemental blended and mechanical alloying. The microstructure, density, microhardness, compressive, wear, and corrosion properties were characterized. It was found that the volume fraction of β-phase increases with increasing Mo content to around 85%, mainly due to the robust β-phase stabilizer effect. Moreover, the microhardness and compressive properties were enhanced with Mo addition and MA fabrication by 11.5 and 27%, respectively, mainly due to solid solution strengthening, plastic deformation, high dislocations, and lattice defects. However, the strain at failure decreased with decreasing sintered density and increasing porosity. From this study, the corrosion rate decreased with decreasing the porosity, reaching 0.226 × 10−3 mm/year for Ti–12Mo alloy fabricated by elemental blend with a minimum porosity of 3.6%. Ti–Mo alloys can also tolerate properties and impurities, making them suitable for biomedical applications.

The impact of Cu, Ni and Fe2O3 on the magnetic behavior and structural properties of FeSiO2 nanocomposite synthesized through ball milling

The nanocomposite Fe-A/SiO2 soft magnetic materials, with Cu, Ni, and Fe2O3 as dopants, were produced using a mechanical alloying technique. Our central objective was to explore the impact of process parameters on Fe/SiO2 nanocomposite properties. We assessed varying milling time and dopant addition rates, analyzing structural, morphological, and magnetic aspects through SEM, EDS, XRD, and VSM at different synthesis stages. The XRD pattern revealed iron, Fe(Ni), Fe(Cu), and Fe2O3 with an average crystallite size of 28–39 nm and lattice strain of 0.0097%–0.0222%. Notably, the lattice parameters decreased from 0.2852 to 0.2836 nm. Among nanocomposites, FeCu/SiO2 displayed the smallest crystallite size (34.3 nm), while FeNiSiO2 showed the highest lattice parameter (0.2853 nm). The ATR analysis unveiled Si–O–Si stretching vibrations at 1052 cm−1, intensifying with milling time. The inclusion of Cu and Ni in the FeSiO2 system significantly influenced the Si–O–Si bond. Coercivity and remanence magnetization in Fe/SiO2 increased notably with milling time, reaching 68.47 Oe and 8.73 emu g−1, respectively. The Fe/Fe2O3/SiO2 and FeSiO2 nanocomposites exhibited the maximum values of coercivity (47.07 Oe) and remanence magnetization (12.24 emu g−1). Remarkably, the Fe/SiO2 nanocomposite displayed the highest saturation magnetization, measuring an impressive 176.07 emu g−1 after 30 h of milling, while FeCu/SiO2 reached 165.64 emu g−1 after 20 h. Overall, our findings suggest the Fe/SiO2 nanocomposite as a promising high-frequency soft magnetic material.

Effect of Indium on the Properties of Mg-Zn-Based Alloys

In this study, indium was added to the binary Mg-Zn alloy to prepare an ultrafine-grained ternary Mg-Zn-In alloy with enhanced mechanical and corrosion properties. The bulk Mg-Zn-In alloy was synthesized through a combination of mechanical alloying and powder metallurgy techniques. The SPEX 8000 mixer mill was used to carry out the process under an argon atmosphere. The mixed powders were mechanically alloyed for 24 h. The mixture was uniaxially pressed at a compacting pressure of 600 MPa. The green compacts were sintered under a protective argon atmosphere at 300 °C for 1 h. The evolution of the microstructural, mechanical, and corrosion properties of Mg-based alloys was studied. X-ray diffraction and scanning electron microscopy were used to analyze the phase and microstructure. The changes in hardness and corrosion properties were also measured. Compared to binary Mg-Zn alloy samples modified with In, the samples exhibited a higher microhardness, which can be related to structure refinement and phase distribution. Based on the results of electrochemical testing, it was observed that the modified samples exhibited an improved level of corrosion resistance compared to the Mg-Zn binary alloy.

Extraordinary role of Nd3+ doping on high temperature stable multiferroic and magneto electric properties of Bi1-xNdxFeO3-Bi2Fe4O9/Sr1-xCaxTiO3 dual phase ceramic composite

The Bi1-xNdxFeO3-Bi2Fe4O9/Sr1-xCaxTiO3 (BNFO-SCT) ceramic material displays multiferroic properties after being synthesized via using both the traditional solid-state method and the mechanical alloying technique. Nd3+ was added to the BNFO-SCT as a dopant, and the effects on the microstructure, dielectric characteristics, ferroelectric properties, and piezoelectric properties were examined using a variety of analytical techniques. With addition of Nd3+ dopants in BNFO-SCT, a two-phase structure that changed from rhombohedral perovskite (R3c) to triclinic (P1) and a significant increase in dielectric properties were observed. The remnant polarization, coercive electric field, and magnetocapacitance coefficient showed notable enhancement with increasing Nd3+ doping (x) up to 0.6, thereafter, all these properties began to decrease. Moreover, the leakage current of the BNFO-SCT material decreased with higher Nd3+ content. Interestingly, the dielectric properties at room temperature exhibited a substantial increase when subjected to an applied magnetic field.
