Effect of coupled intercritical isothermal holding and rapid heating on bainitic transformation and mechanical properties in medium-carbon nanobainitic steel

Journal of Materials Research and Technology
A coupled intercritical-isothermal–rapid-heating (II-RH) route is proposed to exploit, rather than eliminate, chemical heterogeneity in a bainitic medium-Mn steel (Fe–0.29C-1.97Si–1.0Ni–1.56Mn–1.45Cr).
