Transformations during Intercritical Annealing of a TRIP-assisted Steel.

open access: yesISIJ International, 1998
During intercritical annealing of cold rolled TRIP-assisted steel, ferrite matrix recrystallizes and austenite forms. After subsequent quenching, part of that austenite may remain at room temperature as retained austenite, while the other part transforms into martensite. Based on their respective origin, recrystallized ferrite grains were recognized as

Mechanisms of austenite growth during intercritical annealing in medium manganese steels

open access: yesScripta Materialia, 2022
Abstract The third-generation advanced high strength medium manganese (3–12 wt.%) steels typically consist of ultrafine-grained dual-phase (austenite-ferrite) microstructure, obtained through the intercritical annealing of martensite at temperatures typically ≤  0.5Tmelt, where the bulk diffusion of Mn is extremely slow.
