摘要：
The activation energy for hot deformation (Q(HW)) of high-Mn microalloyed TWIP steels was determined from experimental uniaxial hot compression curves. The presence of microalloying elements such as Nb, V, and Ti, increases the Q(HW) value from 366 in the non-microalloyed one to 446 kJ/mol in the V-microalloyed TWIP steel. This change represents an increase from 16% up to 22% of Q(HW) values. (C) 2012 Elsevier B.V. All rights reserved.
