Fig.3 Phase distribution maps (a1-c1) and orientation maps (a2-c2) of the Fe₅₀Mn₃₀Co₁₀Cr₁₀HEA at the PC state before (a1, a2, b1, b2) and after (c1, c2) deformation taken from different regions (In the phase distribution maps, high-angle boundaries with misorientation angles larger than 10° are indicated by thick black lines, low-angle boundaries with misorientation angles between 3° and 10° are indicated by thin black lines, and Σ3 twin boundaries in the fcc phase are indicated by white solid lines, respectively; RD—rolling direction, ND—normal direction, LD—loading direction)
