Immiscible metals due to their inherent specs are insoluble over the steady state. Developing an innovative approach to this issue would be fascinating and challenge the overriding rules. Herein, we proffer the principles of synthesis of Cu-Nb nanocomposites using electrochemical deoxidation route. This method consists of the cathodic electrolysis of the nanoparticles Cu-Nb2O5 through the...

in this research, the high-energy planetary mill was employed to produce nanocrystalline ti-50al(γ)(at%) powders. initial powders were mechanically alloyed in 99.9999% and 90% purities of argon and also air atmosphere with alloying times up to 50h. the effect of impurity of argon atmosphere on the microstructure and the rate of phase transformation of ti-50al were investigated during mechanical...

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...

The electrical and thermal contact resistances are key parameters for obtaining an accurate electro-thermal model of the spark plasma sintering (SPS) process. However, due to lack a general expression, these usually determined empirically. Thus, they only valid specific material SPS configuration. A simple method based on limited amount experiments as well new formulation developed. First, evol...

EDM is an unconventional electro thermal machining process used for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining process. The process involves a controlled erosion of electrically conductive materials by the initiation of rapid and repetitive spark discharges between the tool and work piece separated by a small gap ...

The main objective of this study was to develop a high-entropy alloy (HEA) derived from the CoxCrFeNiTi HEA system (x = 0.5, 1) for protective coatings using magnetron sputtering method. In order produce targets required process, mechanically alloyed metallic powders were consolidated via spark plasma sintering (SPS). microstructural analysis results mixture presented morphology changes after 3...
