Figure 5. EBSD of Fe40Mn20Cr20Ni20 HEA annealed at 700 and 900 °C for 2 h after tensile fracture at cryogenic temperature: (a1 and b1) phase maps; (a2 and b2) IPF diagrams; (a3 and b3) grain boundary diagrams, where the black solid lines represent the large-angle grain boundaries and the red solid lines denote the twin boundaries; (a4 and b4) KAM maps. EBSD: Electron backscattering diffraction; HEA: high-entropy alloy.
