چکیده انگلیسی
The transformation-induced plasticity (TRIP) effect and resistance characteristics to adiabatic shear failure at high strain rates of high-manganese steel were investigated by using scanning electron microscopy and electron backscattering diffraction. Results showed that the high-manganese steel exhibited excellent strain hardening effect and resistance to adiabatic shear failure because of the TRIP effect. The TRIP effect occurred during dynamic deformation and showed two distinct stages, namely, the smooth TRIP process before the formation of adiabatic shear band (ASB) and the inhibited TRIP process during further deformation. In the first stage, the martensitic transformation showed slight orientation dependence and weak variant selection, which promoted the TRIP effect. In the second stage, reverse martensitic transformation occurred. Adiabatic shear bands (ASBs) developed typical shear microtextures {111}<1¯10>. In microtextures, two groups of fine grains are in a twin relationship and uniform distribution, which restrained the formation of holes and cracks within the ASBs and enhanced damage resistance after ASB formation.
