Influence of Mn on nanobainite formation kinetics and austenite retention in Al-added medium-Mn steels subjected to hybrid isothermal annealing

This study investigates the bainite transformation kinetics, microstructural evolution, and mechanical properties of Al-alloyed 3MnNb and 4MnNb multiphase steels subjected to a novel hybrid heat treatment. Dilatometric analysis revealed that bainite formation in the 3MnNb steel initiates more rapidl...
