The developments of Al and V free, biocompatible Ti-alloy have been the subject researcher in orthopedic joints replacement domain. current article addresses methodology chosen for design, machinability, low-cost surface texturing process a high degree biocompatibility. It is evident that an astonishing increase biocompatibility can be achieved by synchronizing electro-discharge spark energy wi...

Pure magnesium (Mg) powders together with pure titanium (Ti) were mechanically alloyed (MAed) using a vibration ball mill. Stearic acid was used as process control agent (PCA) for the mechanical alloying (MA) process. The MAed consolidated into bulk materials by spark plasma sintering (SPS). Changes in hardness and solid-state reactions of SPS have been examined measurements an X-ray diffractio...

This paper deals with the effect of microstructure condition on ignition temperature, mechanical and corrosion properties commercial WE43 alloy prepared by various processing techniques including conventional casting, extrusion, powder metallurgy methods such as spark plasma sintering. For different technique, differences in microstructures were observed, grain sizes, intermetallic phases, amou...

Temperature is one of the effective parameters in erosion of spark plug electrodes. In this research, temperature of spark plug was measured in engine's different operation conditions with two types of fuels: compressed natural gas and gasoline. Test results showed that, temperature of center electrode is lower than ground electrode and maximum difference between them is 110ºC that occurs at...

An investigation was conducted to explore the applicability of eddy current and microwave techniques to characterize grains size variation during mechanical alloying. A series of Nanocrystalline (Fe65Co35)70Al30 samples have been prepared, these structures are prepared using mechanical alloying based on planetary ball mill under several milling conditions. Mechanical alloying is a non-equilibri...

The alloying behaviour of materials is a well-known problem in all kinds of compounds. Revealing the heteroatomic distributions in two-dimensional crystals is particularly critical for their practical use as nano-devices. Here we obtain statistics of the homo- and heteroatomic coordinates in single-layered Mo(1-x)W(x)S(2) from the atomically resolved scanning transmission electron microscope im...

Flash sintering is a very promising method with great potential for the ultra-rapid production of objects firing processes mere seconds. However, transition from few millimeters samples to larger scales key issue. In this study, we explore spark plasma approach allowing stable hybrid heating in flash condition and producing near net shape sintered specimens. Two electric current configurations ...
