Interaction between recrystallization and austenite formation in cold- rolled dual-phase steels during non-isothermal intercritical treatments. Mélanie, O., Véronique, M., Damien, F., Michel, P., Eric, B., & Fanny, K.
abstract   bibtex   
Recrystallization (ReX) was monitored in a dual-phase cold-rolled 0.17wt%C steel thanks to microhardness measurements combined with microstructural observations. Isothermal ReX kinetics was modeled by a Johnson-Mehl-Avrami-Kolmogorov (JMAK) law. JMAK parameters were determined through (i) a time-temperature equivalence which enabled to define a physically based activation energy, and, (ii) a linearization of the equation which led to determine a unique Avrami exponent coefficient of the JMAK law. The obtained parameterization was extended to predict ReX progress during non-isothermal complex cycles including heating and holding stages. It was then successfully validated with experiments. Finally, ReX progress was confronted to austenite formation to shed some light on the interaction between ReX and austenite formation.
