Microstructure and mechanical properties of lightweight AlCrTiV_(0.5)Cu_(x) high-entropy alloys

摘要

High-entropy alloys(HEAs)are an emerging and rapidly developing family of alloys with appealing properties such as lightweight HEAs with excellent mechanical properties.In this study,to obtain lightweight HEAs with exceptional hardness,we prepared AlCrTiV_(0.5)Cu_(x)(x=0,0.2,0.4,0.6,0.8 and 1.0,denoted as Cu_(0),Cu_(0.2),Cu_(0.4),Cu_(0.6),Cu_(0.8) and Cu_(1.0) alloys,respectively)HEAs and analyzed their microstructure and hardness.
