Design concept and phase transformation study of advanced bainitic-austenitic medium-Mn steel [PDF]
Scientific ReportsThe isothermal heat treatment processing routes are designed for a novel 0.17 C-3.1Mn-1Si-0.55Al-0.22Mo-0.034Ti-0.073 V steel, aiming to obtain a homogeneous fine lath-type microstructure consisting of bainitic ferrite and retained austenite (RA).

Improving Strength-Ductility via Short Austenitization in a Low-Carbon Carbide-Free Bainitic Steel
Crystals, 2022 The strength and ductility of low-carbon carbide-free bainitic (CFB) automotive steel are not good enough. In this study, a short austenitization (SA) process in conjunction with isothermal bainitic transformation was adopted to refine the bainitic ...
