Effect of prior austenite grain size on strength-ductility trade-off, phase evolution, and fracture behavior in a fully austenitizated QP steel: Insights into TRIP behavior

Effect of prior austenite grain size on strength-ductility trade-off, phase evolution, and fracture behavior in a fully austenitizated QP steel: Insights into TRIP behavior

This study investigates the effects of primary austenite grain size (PAGS) on the strength-ductility balance, phase development, and fracture properties of hot-forged quench and partitioning (QP) steels (Fe-0.23 %C-1.25 %Si-1.77 %Mn), which were fully austenitized at five different temperature-time...
