Alloying elements greatly influence phase transformation kinetics in steel due to local partitioning and interfacial segregation to migrating interface and quantitative understanding of the alloying effects is a key for tailoring mechanical properties of modern high strength steels. Energy dissipation for interface migration is an important concept to understand the alloying effects and also to control carbon enrichment in untransformed austenite in multiphase high strength TRIP or DP steels. In this review, possible sources causing energy dissipation for interface migration are introduced and the energy dissipation for interface migration in formations of grain boundary ferrite (α), Widmanstatten α and bainitic α investigated in various systems are summarized.
