Crystallographic Behaviors of Uni-Axial Deformed High Manganese Steels

Abstract:

High manganese TRIP/TWIP steels with different Mn contents were subjected to uniaxial deformation. The textures, misorientations and orientation relationships were determined in austenite, HCP/BCC martensites and ferrite. It is observed that the mechanically stabilized austenite possesses mainly stable deformation texture, the intermediate HCP martensite possesses mainly unstable tilted basal texture and the BCC martensite possesses stable deformation texture which was actually mixed with transformation texture. Special misorientations due to either the inherence from austenite or due to twins or variant selection were main components in each phase. K-S relationship became much scattered due to slip-induced misorientations both in martensite and in parent austenite.
