Abstract:

Al25Ni25W25Cr20V5 refractory high entropy alloy (RHEAs) was synthesised by mechanical alloying (MA) and its characterization study and mechanical behaviour of this prepared refractory high entropy alloy was investigated in this research work. After 18 hr of mechanical alloying, fine grained microstructure was obtained and homogeneous distribution of all metal elements was achieved. Crystallite size, lattice strain and phase analysis of prepared RHEAs powders were calculated through X-ray diffraction (XRD) techniques. Morphological study of prepared RHEAs powders was investigated through scanning electron microscopy (SEM). Aluminium, Nickel, Tungsten, Chromium and vanadium elements presented in the prepared RHEAs were identified through Energy dispersive spectrum analysis (EDAX). After milling, powders were compacted and sintered at two temperatures such as 600°C and 800°C. Density, porosity and Vickers micro hardness measurements were taken after sintered at 600°C and 800°C. The results indicate that the sintering environment and conditions will affect the mechanical properties of developed Al25Ni25W25Cr20V5 refractory high entropy alloy.
