The effect of grain size and stacking fault energy on the mechanical properties of an FCC-based non-equiatomic Cr₂₀Mn₂₀Fe₂₀Co_40-xNi_x high-entropy alloy (HEA) was investigated in the present work. The alloy samples were processed using thermo-mechanical processing and then subjected to mechanical testing coupled with EBSD and TEM.
