1.Introduction
Equimolar　multicomponent　design　and　maximized　configura-tional　entropy　cause　high-entropy　alloys(HEAs)to　have　outstand-ing　mechanical　performance　over　a　large　temperature　range　from　cryogenic　temperatures　up　to　room　temperature[1-9].Accord-ing　to　previous　studies,deformation-induced　twinning　and　phase　transformation　are　two　athermal　transformations　that　significantly　improve　the　mechanical　performance　of　HEAs,especially　those　with　face-centered　cubic(FCC)structure[8,10-19].
