- Abstract
- Tensile deformation behavior of the Fe-18Mn-1.5Al-0.6C twinning-induced plasticity steel has been investigated at room temperature, − 125 °C, and − 196 °C. The steel shows the largest ductility at − 125 °C and the smallest ductility at − 196 °C. While work hardening rate continuously decreases with strain at − 196 °C, the specimens tested at other temperatures show a stage where work hardening rate continuously increases with strain, which is more evident at − 125 °C. Stacking faults form most actively at − 125 °C and this contributes to a continuous increase in work hardening rate with strain and an increase in ductility at − 125 °C.
