Dependence of deformation twinning on grain orientation in compressed high manganese steels

Electron backscattered diffraction reveals the dependence of deformation twinning on grain orientation and distinct grain rotations during compression of high manganese steels. This leads to the evolution of a special microstructure and restricts the kinetics of twinning in comparison with tension deformation. The macrotexture exhibits twin relationships among texture components, produced by twinning at low strain.
