Quasi-cleavage Fracture along Annealing Twin Boundaries in a Fe-Mn-C Austenitic Steel

摘要

Martensitic transformation from FCC (γ) to HCP (ε) is often observed in austenitic high Mn steels. For example, the ε-martensitic transformation occurs at cryogenic temper ature in twinning induced plasticity steels and at room temperature in shape memory alloys.
