Strain-hardening of twinning-induced plasticity steels

The mechanisms of and the different theoretical approaches dedicated to the strain hardening of twinning-induced plasticity steels are presented and discussed using results available in the literature. The analysis shows that twinning is the first-order mechanism explaining the impressive strain hardening, and modeling is now available for an accurate description, including the effect of carbon content.
