Improving impact toughness of Fe–20Mn–9Al-1.5C–2Ni–3Cr low-density steel by optimizing grain boundaries via multi-stage heat treatment without compromising high strength and ductility

Improving impact toughness of Fe–20Mn–9Al-1.5C–2Ni–3Cr low-density steel by optimizing grain boundaries via multi-stage heat treatment without compromising high strength and ductility

Fe–20Mn–9Al-1.5C–2Ni–3Cr low-density steel is subjected to multi-stage heat treatment (MHT) to improve the toughness while maintaining high strength and ductility. The mechanical properties and fracture behavior of MHT steel are compared with those resulting from single-stage heat treatment (S1000 a...
