The coupling of multiple advanced characterization techniques performed on a Fe-0.2C-3.4Mn-1.6Si, austenitic-martensitic, Quench and Partition steel (Q&P) with ultrahigh strength (∼1.5 GPa) microscopically explains its high true strain at fracture (ɛf) and superior toughness. The benefits of Tra...
