Abstract
The AlCrFeCuNi-(Vx) High Entropy Alloy (HEA) was created via arc-melting and casting processes. The influence of vanadium (V) on the Nano mechanical behaviour, microstructural development, as well as the wear performance of the produced HEAs was examined. Notable improvements to the Nano hardness of the HEAs were evident with an increase in V content from 1at% to 5at%. The addition of V altered the frictional behaviour of the HEA with an increased coefficient of friction as V is increased. The addition of V also greatly affected the microstructural orientation of the HEA, exhibiting signs of homogenization as V content increased.
