Study on the influence of processing technology on the properties of 2024-T3 aluminum alloy

2024-T3 aluminum alloy is widely recognized for its low density and excellent mechanical properties. However, it has some shortcomings at high temperatures. Using Abaqus simulation technology, the surface heat source during the VIES (Variable Input Energy Source) treatment process was simulated, with the energy originating from the discharge channel. Through orthogonal experimental methods, it was indicated that the distribution and depth of the molten pool varied under different process parameters. Meanwhile, electric spark surface strengthening mainly affected the surface of the workpiece, with minimal impact on the internal structure. When the impact frequency is constant, increasing the input current enlarges the maximum heat flux density (Qmax) at the center, leading to an expansion of the molten pool area. Conversely, when the input current is constant, increasing the impact frequency shortens the contact time between the electric spark and the plate, resulting in reduced heat input from the electric spark. Consequently, the surface molten pool area decreases.

The influence of processing technologies on the differentiation of soil layers by the content of mobile components of organic matter

It is shown that shallow flat-cut tillage contributes to the formation of water-soluble organic matter and causes a significant differentiation of 0-10 and 10-20 cm of the layer according to the content of mobile organic matter. The use of tools with plane-cutting working organs contributed to the accumulation of a plant residues mass, the microbiological activation of their transformation processes and the accumulation of young organic compounds in the upper part of the root layer, significantly exceeding the layer of 10-20 cm.

Technological features of the production of welded beds from prefabricated base parts

The work is devoted to the problem of fatigue strength of welded-cast joints as applied to the operating conditions of body parts of machines. Such operating conditions are characterized by non-uniformity of intensity and concentration of the load on parts and assemblies during the operation of the equipment. This heterogeneity of the load actualizes production of precisely welded-cast base parts for metalworking equipment beds. This is of considerable technological and economic interest. The aim of the work is to study the strength of welded-cast bearing structures in relation to the work of beds of heavy lathes. Unalloyed medium-carbon structural steel 35L and steel of ordinary quality MCT3 in the form of rolled products were used as the main materials for research. The research methods are presented. The study of the structure and properties of the welded joint made it possible to assess the technical feasibility of using the studied metals in the manufacture of welded-cast bearing structures. It has been established that welding of steel castings with rolled steel causes significant structural and mechanical heterogeneity. The influence of processing technology on the nature of formation of the structure of welded-cast joints is presented. The influence of heat treatment on the value of the hardness of the welded seam and the heat-affected zone was investigated. The study of the fatigue resistance of welded-cast specimens was carried out in relation to the operating conditions of joints undergoing vibration loads at normal temperatures, which can be classified as fatigue with a symmetric load cycle. It was found that the use of heat treatment of welded-cast specimens significantly reduces the mechanical heterogeneity of the joint along the seam and the heat-affected zone. Based on the results of studying mechanical characteristics, the choice of technology for the production of welded-cast joints is justified.

Influence of Processing Technology on Electrochemical Corrosion Behavior of Ti-6Al-4V Alloys

Ti-6Al-4V alloys are typically used for biomedical implants, aerospace components, and offshore equipment, where corrosion resistance is critical. In the present paper, the electrochemical corrosion behaviors of Ti-6Al-4V alloys made by different traditional processing and 3D printing technologies in seawater, 3.5 wt% NaCl, 3.5 wt% HCl, 5 wt% HCl, and 10 wt% HCl solutions were studied through polarization curve and electrochemical impedance spectra analyses. The influences of microstructure and printing parameters on the corrosion behaviors of Ti-6Al-4V alloys were analyzed. In addition, the corrosion current density, film resistance, and charge transfer resistance of traditionally processed Ti-6Al-4V and 3D-printed Ti-6Al-4V in the five solutions were compared. The results show that Ti-6Al-4V possesses a better corrosion resistance in seawater than in 3.5 wt% NaCl, and that the corrosion rate increases with the HCl concentration. Besides, 3D printed Ti-6Al-4V shows a higher corrosion rate in comparison with traditionally processed Ti-6Al-4V because pores are effortless to enrich Cl−. Finally, the ratio of laser power to its scanning speed and the phase constituent composition of the alloy have slight influences on its electrochemical corrosion behavior. It is suggested that, for the 3D-printed alloy, the deterioration of mechanical properties induced by corrosion damage during servicing should be assessed and considered.

FATIGUE STRENGTH IMPROVEMENT OF STEEL ROLLERS IN CONVEYOR BELTS WHEN USING SHOT PEENING

Numerous factors influence the tribological wear of steel rollers used in conveyor belts. The difficulty in precise determination of these factors results from, among others, a complex and not completely explored wear mechanism. Corrosive and fatigue damages of conveyor belt rollers start mainly on the surface. The present article describes studies on the influence of processing technology of the roller surface by means of the shot peening method in the context of fatigue strength improvement. Compressive stresses formed due to shot peening reach the maximum value just below the roller surface. The values of compressive stresses reach about half of the proof stress of the steel from which they are made. In results of the carried out experimental model tests, it was found that it is possible to significantly improve the properties of the top surface layer of the roller surface, and especially to increase fatigue strength, fatigue corrosion resistance, resistance to cracking caused by stress corrosion, and the like.

Influence of processing technology on fracture feature of Ti6Al4V

Selective laser melting is an advanced manufacturing technology providing alternative method of producing complex components directly from 3D computer models. The paper is focused on problems related with selective laser melting technology (SLM) used for preparing titanium based implants. Two series of ten Ti6Al4V samples were mechanically tested in tension and compression respectively before and after heat treatment. Annealing under argon atmosphere consisted of solution treatment at 955 °C followed by furnace cooling to 855 °C with water quenching and ageing at 600 °C with air cooling. Fractography study of fracture surfaces was performed using scanning electron microscopy and the observation was correlated with structural and mechanical properties of the SLM specimens in the condition as-built or heat treated. The failure features of as-built specimens corresponded to the microstructure with relatively high porosity, martensite needles, microcracks and residual stresses. The heat treatment resulted in the transformation of martensite to (alpha + beta) lamellar structure modifying plastic properties that corresponded to the morphology of fracture surfaces. In spite of the porosity occurrence both specimen series exhibited high mechanical properties in tension as well as in compression.

RESEARCH OF CRANBERRY MAIN INDICATORS OF CHEMICAL COMPOSITION AND ITS PROCESSING PRODUCTS

It is well–known that cranberry is an especially rich and heterogenic source of phytochemical substances. Modern technologies allow to produce food products of wild fruits and berries, but they use their diverse and useful chemical composition insufficiently. The aim of the work was in studying features of the chemical composition and content of biologically active substances in cranberries, harvested at the territory of Ukraine, and the influence of processing technologies of cranberry on main indicators of its chemical composition at producing juices. It was established, that the maximal extraction of biologically active substances is possible at juices production using biocatalysis method, because the essential part of functional elements in the raw material is in the bound condition and is a base of cellular walls that is why it is expedient to disturb nativity and integrity of these natural biopolymers. There was experimentally grounded the influence of a processing technology on the quality of cranberry juice. There was studied the phenol composition of cranberry composition and influence of different ways of fermentolysis on PS extraction. It was confirmed by results of the study of the fraction composition of phenol substances, that their maximal extraction is achieved after the enzymatic processing of pulp and momentary heating to inactivate the effect of enzymatic preparations. It was proved, that enzymatic biocatalysis of cranberry pulp also favors the essential increase of the output of organic acids (lemon, apple, amber), sugars (fructose, glucose), sorbite polyalcohol and also phenol substances of cranberries. The mechanism of the enzymatic complex influence on cranberry pulp at fermentolysis was demonstrated. The use of products of cranberries processing at food products manufacturing will allow: to enrich the chemical composition, to compensate deviations of functional–technical properties of the raw material and to introduce resource–saving technologies. Based on the researches there were substantiated perspectives of using juices and marc of cranberry in different branches of the food industry: non–alcoholic, meat processing and at manufacturing products of the restaurant industry.

Thermo-economic optimisation of the polygeneration of synthetic natural gas (SNG), power and heat from lignocellulosic biomass by gasification and methanation

After a brief review of the current research on the production of synthetic natural gas (SNG) from lignocellulosic biomass by gasification and methanation, this paper presents detailed thermo-economic process optimisation of the polygeneration of SNG, power and heat. Based on a previously developed model, all suitable candidate configurations of a superstructure of promising technologies for the individual conversion steps are optimised with respect to the overall efficiency and investement cost with an evolutionary, multi-objective algorithm. In an extensive analysis, the influence of process technology, operating conditions and process integration on the thermo-economic performance is discussed and the best technology matches are determined. Systematically optimised flowsheets might thereby convert 66 to 75% of the dry wood's lower heating value to SNG while cogenerating a considerable amount of power and/or industrial heat. In order to provide a general database of optimal plant configurations, cost exponents that quantify the economies of scale are regressed, and the most profitable flowsheets are identified for different energy price scenarios and scale. A comparison with current literature on SNG production from biomass reveals the potential of applying such systematic process systems engineering approaches for the design of energy- and cost-efficient biofuel plants.

The microstructure of selected states was analyzed by transmission electron microscopy.

Influence of Process Technology on DC-Performance of GaN-Based HFETs

This work reports on the influence of the surface and the gate length on the performance of AlGaN/GaN based Hetero Field Effect Transistors (HFETs). Differently NH4Sx treated surfaces result in variation of the drain current IDmax of more then 100%. Gate recessing by photoelectrochemical treatment changes the threshold voltage Vth but affects the drain current little. Next, the reduction of the gate length increases the IDmax further by more than 60%. The IDmax values for the transistors are 350 mA mm—1 for the NH4Sx-treated, 850 mA for the untreated, and 1.43 A mm—1 for the one with a 0.2 μm gate length. The corresponding transconductances gm are 66, 150, and 280 mS mm—1, respectively. Surface analysis with Auger Electron Spectroscopy (AES) and contact characterization (TLM) reveals, that the NH4Sx treatment removes the native oxide and increases the contact resistance as well. Therefore we attribute the increase of IDmax and gm mainly to a beneficial behavior of gallium-oxide at the surface on the sheet carrier density nS of the 2DEG at the heterointerface.

Technology and Supervisory Functions: A Preliminary View

In the last decade, a modest number of investigations have been undertaken which probe the relationship between supervisory functions and the level of technological attainment or refinement. To the extent that results have been available, variation in content and method has compounded the problem of discerning possible relationships among the variables comprising process technology and supervisory organization and activities. This paper reports an exploratory field study dealing with the influence of process technology on two important functional activities of supervision, Direction and Control. Two high-volume production units within baking industry, one more technologically advanced than the other, provided the basis for the development of comparative data and information. Supervisors in the more advanced technological system devoted significantly less time to direction and control activities. This difference in allocation of supervisory time and variation in supervisory practices suggests some of the organizational necessities evolving from an advanced technology. In addition, the potential diminution of such historically important supervisory functions as direction and control points to changes in the composition of functional supervisory activities as more advanced states of technology are realized.
