In situ neutron diffraction and crystal plasticity analysis on Q&P1180 steel during plastic deformation

Q&P1180 is a typical third generation of advanced high strength steel. In this paper, the microstructure evolution of the Q&P1180 steel during uniaxial tension is investigated comprehensively by using in situ neutron diffraction technique, electron backscatter diffraction (EBSD), scanning electron microscope (SEM) and the elastic-visco-plastic self-consistent with phase transformation (EVPSC-PT) model. Tempered martensite (TM) is determined as …
