Abstract

In the previous paper, carbon concentration dependence of deformation twinning behavior in twinning-induced plasticity steels had been investigated, which clarified that the deformation twin fraction in the 〈144〉 tensile orientation did not change against carbon concentration. Additionally, in this paper, twinning deformation occurred in the Fe-18Mn-1.2C steel at 473 K with relatively high stacking fault energy of 55 mJ/m². To explain these experimental results, dynamic strain aging of Shockley partials dislocations was proposed as an additional contributing the high stacking fault energy in Fe-Mn-C austenitic steels were interpreted by considering the influence of dynamic strain aging. factor to assist the deformation twinning in high carbon-added austenitic steels. Most abnormalities about deformation twinning such as the high stacking fault energy in Fe-Mn-C austenitic steels were interpreted by considering the influence of dynamic strain aging.
