The impact of the nonionic surfactant, dodecyl triethyleneglycol ether (C(12)E(3)) on the solution microstructure of the dialkyl chain cationic surfactant, dihexadecyl dimethyl ammonium bromide, (DHDAB) has been investigated. The variation in solution microstructure has been studied using a combination of small angle neutron scattering, ultra small angle neutron scattering, optical texture and ...
High-entropy alloys are known to possed good mechanical properties which usually related the preparation technique. In this work, CoCrFeNiMnXAl20-X (X=5, 10, 15) were prepared by a combination of alloying (MA) and com-pacted via spark plasma sintering (SPS). Such materials examined for their phase composition microstructure. Furthermore, as result content Mn/Al determined. It was found, that pa...
2024 Aluminum alloy was squeezed cast by the Gas Induced Semi Solid (GISS) process. Effect of artificial aging on microstructure and mechanical properties of this alloy was studied in the present work. The solutionized specimens were aged hardened at temperatures of 175°C, 200°C, and 225°C under various time durations. The highest hardness of about 77.7 HRE was attained from specimen aged at th...
Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties. Steel thixoforging faces more challenges as compared to that of low melting point materials due to high processing temperature and lack of understanding of the thermomechanical behavior of ma...
Lead-rich solid industrial wastes were vitrified by the addition of glass formers in various concentrations, to produce non-toxic vitreous stabilized products that can be freely disposed or used as construction materials. Toxicity of both the as-received industrial solid waste and the stabilized products was determined using standard leaching test procedures. The chemically stable vitreous prod...
In this study, joining of Ni3Al intermetallic compounds using the transient liquid phase (TLP) process with Cu interlayer was investigated. The binding process was carried out in a vacuum furnace at a temperature of 1050 °C for different times of 30, 60, 90 and 120 minutes. The effect of time variation on microstructure and mechanical properties of the joint zone was investigated. The EDS analy...
We present an in-silico model of avascular poroelastic tumour growth coupled with a multiscale biphasic description of the tumour-host environment. The model is specified to in-vitro data, facilitating biophysically realistic simulations of tumour spheroid growth into a dense collagen hydrogel. We use the model to first confirm that passive mechanical remodelling of collagen fibres at the tumou...
Friction stir extrusion (FSE) was used with WE43 Mg to create a rod hybrid microstructure. The rod’s electrochemical corrosion response characterized in Hank’s balanced salt solution at 37 ± 1 °C. showed refined grains near the edge, while coarse were observed center. A larger fraction of precipitates edge possibly hindering grain growth. and presence regions resulted higher hardness owing conf...
