摘要：
The effects of Al/Ni content on mechanical properties of AlxCrFeNi(2-x)Ti0.2 high-entropy alloys was investigated. A novel Al0.5CrFeNi1.5Ti0.2 alloy with a dual eutectic microstructure and ultrafine grains was developed. This microstructure comprises a first-level eutectic structure, which consists of soft FCC and hard BCC phases, and a second-level eutectic structure, which is present in the BCC regions and consists of disordered A2 and ordered B2 phases, as well as the presence of nanoscale A2 precipitates within the B2 phase. The alloy exhibits excellent ultimate compressive strength (similar to 3717 MPa) and plasticity (similar to 42 %), while also exhibiting a high ultimate tensile strength of similar to 1220 MPa and a notable superelasticity of 4.4 %.
