Abstract
High manganese austenitic TWIP steels are of great potential in the field of transportation-related industries owing to their exceptional combination of strength and ductility. A series of compression experiments were conducted on a Fe-18Mn-0.6C-1.5Al alloy at various strain rates (from 1.0 × 10 -2 to 6.4 × 103 s-1) and total strains (≈15 and ≈20%) with a Gleeble 3500 thermo-mechanical simulator and a Split Hopkinson Pressure Bar system. Under compressive deformation, results showed this alloy possessed excellent strain-hardening behavior, attributed to the occurrence of mechanical twinning during deformation. The prevailing deformation mechanism was observed to be twinning, which was substa..
