Abstract
Driven by the concept of high entropy alloy, Mg62.9Li30Al3Y1.3Gd1.5Sc1.3 (at. %), a new multicomponent alloy is designed to solve the brittleness of lightweight high entropy alloys (LWHEAs). The microstructure and mechanical properties are also studied. As cast, the alloy consists of bcc solid solution phase with a large number of second phases and stands out for the low density (1.62 g/cm3) and the high compression strain (>45 %). Then two typical deformation processes, cold rolling and equal channel angular pressing (ECAP), were applied to improve the strength. After cold rolling, the ultimate tensile strength improved from 107 MPa to 145 MPa and the ductility increased by two times; After ECAP processing, the ultimate tensile strength considerably increased to 211 MPa without ductility loss.
