Effect of Cold Rolling on the Microstructure and Hardness of Al₅Cr₁₂Fe₃₅Mn₂₈Ni₂₀ High Entropy Alloy

Abstract:

The microstructure and hardness changes of a non-equiatomic Al₅Cr₁₂Fe₃₅Mn₂₈Ni₂₀high-entropy-alloys (HEA) with cold rolling are presented here. Using a variety of characterization methods, it is shown that the alloy is single FCC phase structure which doesn't change with cold rolling up to90%CR. With increasing the cold rolling reduction ratio, the hardness increased and the dendritic structures are broken and refined.
