Similarly, it is proposed here to consider the effective grain size for a non-recrystallized austenite to describe the kinetics of ferrite formation in the framework of a mixed-mode model [6] that has already been applied to describe the austenite decomposition from recrystallized austenite in a number of advanced high strength steels [2-3,5].
Capturing the kinetics of austenite decomposition for both recrystallized and non-recrystallized cases with one set of parameters confirms the versatile capability of the proposed modeling framework Acknowledgments The authors wish to thank the Natural Sciences and Engineering and Research Council of Canada and Dofasco Inc. for providing the financial support; Dofasco Inc. supplied also the material for this study.

These transition metal elements have s, p and d electrons that can interact and influence various properties by the advanced electron cloud interaction and hybridization; the degree of β-phase stability is affected by the concentration of the aforementioned elements and the resulting final phases usually contain varying metastable products after rapid cooling and cold deformation.
