Abstract

The influence of strain rate and grain size on the mechanical properties of a 22% Mn, 0.6% C (mass %) austenitic TWIP steel has been studied. A typical quasi-linear stress-strain behaviour of TWIP steels that deform by twinning has been observed at strain rates of 9.4 s⁻¹ and 265 s⁻¹ and room temperature. At high strain rates, the constant work - hardening rate region typically observed in TWIP steel clearly shortens. In addition, the Hall-Petch relationship has been obtained for each strain rate. The Hall-Petch slope K_HP increases as a function of strain in all cases. The dependence of the K_HP on the strain rate could be adiabatic heating.
