Deformation substructural evolution in transformation-induced plasticity high-entropy alloy during cold rolling

Abstract Electron backscatter diffraction (EBSD) technique is used to systematically investigate deformation substructural evolution of the boron-doped high entropy alloy (Fe49.97Mn30Co10Cr10B0.03) with transformation-induced plasticity effect (γ → e phase transformation). As the strain increases, the activated deformation mechanism is in the following orders: slip dislocation in γ phase, the coexisting of slip dislocation in γ phase and γ → e phase transformation, γ → e transformation, dislocation slip in e phase. Correspondingly, the deformation substructure evolution is symmetrically illustrated.
