Abstract

The effect of the addition of copper on the mechanical behavior of a Fe-12%Mn-0.7%C-1.0%Al twinning-induced plasticity steel was investigated by analysis of the mechanical properties obtained in uniaxial tensile tests by means of a physically based constitutive model. The addition of copper was found to retard the kinetics of twin formation and influenced the type of serrations on the stress-strain curve. The copper additions also resulted in a remarkable increase in total elongation without a loss of strength.
