Tempering Behavior of Ductile 1700 MPa Mn-Si-Cr-C Steel Treated by Quenching and Partitioning Process Incorporating Bainite Formation

We obtained a good combination of strength and ductility in a 0.4C-2.0Mn-1.7Si-0.4Cr(wt%) steel,namely,~1.7 GPa of ultimate tensile strength and ~26% of elongation,by conducting a Q-P-T(quenching-partitioning- tempering) process incorporating the formation of carbide-free bainite. The tempering beha...
