Abstract

Abstract

In this study, an optimum design of bainite phase in the commercial quenching and partitioning (Q&P) steel was achieved through the combined results from thermodynamics, kinetics analysis and the pilot experiments. Considering the complex microstructure evolution during partitioning stage of the Q&P treatment, especially the precipitation characteristics of carbides in martensite and their influence on the expansion result, the Boheman model was established and further revised based on the result of expansion experiment. A kinetic model of isothermal bainitic transformation was also set up to simulate this transformation accurately. According to the predicated result from the revised Bohemen model, the effect of the interaction between bainite and martensite on volume fraction and stability of retained austenite was analyzed. The results show that at a low quenching temperature, retained austenite between martensitic laths has a higher volume fraction and plays a dominant role during the deformation. On the contrary, under high temperature quenching condition the volume fraction of retained austenite in bainite is high.
