Continuous annealing of medium-Mn steels: Plasticity controlled by SIMT kinetics through grain size distribution and Mn concentration in retained austenite

Materials & Design
Intercritical annealing, a process widely employed to achieve a high fraction of retained austenite in medium-Mn steels, typically requires several hours, resulting in low economic efficiency. Alternatively, flash annealing, characterized by high heating

Effect of intercritical annealing on microstructure and impact toughness of ultra-low-carbon steel after welding thermal simulation

Journal of Materials Research and Technology
In this paper, the differences of the impact toughness and microstructure of specimens with (IA specimen) and without intercritical annealing (OIA specimen) after welding thermal simulation were compared to illustrate the effect of intercritical ...
