“…Previous studies have shown that the loading rate and the deformation temperature both exert a significant influence on the martensite transformation which takes place during plastic deformation [17,19,20]. Specifically, the volume fraction of ␣ martensite is restricted by the increasing temperature during the adiabatic deformation which occurs during dynamic loading.…”

A model using an energy balance is proposed to describe the volume fraction of multiple-interface martensitic transformations. For martensitic transformations without external stresses at quenching temperature T Ͻ M s , the volume fraction of martensite () is proportional to the undercooling (M s Ϫ T) and inversely proportional to a linear function of the quenching temperature (T); thus, ϭwhere ␤ is a material constant. For stress-induced martensitic transformations under stress with temperature T Ͼ M s , the relationship is ϭ 0 [1 Ϫ ( Ϫ a a ik ik ik )] Ϫ1 , where 0 is the initial detectable amount of martensite formed at martensitic starting stress Ms ik and is a material constant. It is found that the results obtained from this model are in good M s ik ik agreement with experimental results.

Lightweight structural components made of advanced high-strength steels (AHSSs) in the automotive industry can substantially reduce greenhouse gas emissions. The 3rd-generation AHSSs, which consist of medium Mn steel, quenching and partitioning (Q&P) steel, and carbide-free bainitic (CFB) steel, is the current research focus of the steel community. In particular, the retained austenite grains are the intrinsic components of the 3rd-generation AHSSs. These retained austenite grains can demonstrate a transformationinduced plasticity (TRIP) effect by transforming into martensite during mechanical loading, improving the strain-hardening behavior of AHSSs. Consequently, intensive research has been carried out over the past 30 years to understand the role of the TRIP effect on the development of AHSSs. Therefore, this review article is aimed to provide a state-of-the-art summary of recent progress on AHSSs with the TRIP effect. Specifically, the processing, the relationship between microstructure and mechanical properties, and the potential industrial applications of TRIP-enabled AHSSs will be addressed in this review. More importantly, the mechanical stability of the retained austenite grains, which determines the overall performance of the TRIP effect in AHSSs, will be discussed by considering several governing factors.
