Abstract
The Quenching and Partitioning (QP) steels have received increasing attention due to the balance of high strength and good ductility, which results from transformation-induced plasticity (TRIP) effect. In this study, the macroscopic flow behavior and deformation-induced martensitic transformation (DIMT) of QP steels at quasi-static strain rate and elevated temperature have been investigated by uniaxial tension and X-ray diffraction. In addition, temperature increment during quasi-static strain rate tensile tests are measured by infrared camera. A temperature dependent transformation kinetics model considering deformation induced heating is developed to study the explanation of strain rate dependent DIMT. The model indicates that the influence of deformation induced heating at quasi-static strain rate on DIMT is obvious. But, it is insufficient to explain strain rate dependent DIMT solely. Then, an assumption of temperature gradient is introduced to correct the model. The modified model incorporating temperature and strain rate well describes the DIMT behavior of QP steels at quasi-static strain rate and elevated temperature.
