The effect of Cr addition on alloying behavior, microstructure and mechanical properties of multicomponent CoFeNiAl0.5Ti0.5 high entropy alloy (HEA) was studied in detail. Non-equiatomic CoFeNiAl0.5Ti0.5 and CrCoFeNiAl0.5Ti0.5 alloys were fabricated by the combination of mechanical alloying (MA) and...
