摘要：
TRIP-assisted multiphase steels exhibit an excellent balance of strength and ductility, which makes them very attractive for the automotive industry. These remarkable mechanical properties can be attributed mainly to their composite-like microstructures and to the transformation of retained austenite into martensite during straining (Transformation-Induced Plasticity). The aim of this study is to highlight the interactions between the hot rolling conditions, the transformation of austenite and formation of the microstructure, and the resulting mechanical properties. Various rolling simulation techniques were employed to determine how the composite microstructure is formed during the various steps of multi-stage thermomechanical processing.
