摘要: Deformation twinning is widely observed in face-centered cubic (fcc) metals. The stress for activating an important issue to be solved. We presented expression linking based on the total energy change associated with formation of a nucleus according classical nucleation theory. assume there exist no fluctuations overcome barrier. can predict fcc metals, which excellent agreement experimental results simple form. Finally, we introduce measure twinability quantify propensity metals twin as opposed cross-slip.
