»ã±¨ÌáÒª£ºAmorphization due to severe plastic deformation has been discovered in various crystalline materials. In this study, we propose a novel phase field model incorporates the martensite transformation of the austenite phase under large plastic deformation, followed by the intensification of crystal fracture on the martensite phase to form amorphous phase. Simulation results align with experimental data suggest that our phase-field model captures the physical picture of shear-induced amorphization and can predict the threshold for amorphization.
