Transformation Induced Plasticity (TRIP) is one of important effects of steel strengthening mechanism to improve strength, ductility and excellent high-speed deformation behavior. To measure strengthening mechanism of TRIP steel during deformation, in situ neutron diffraction measurement during tensile deformation was performed. Two kinds of TRIP steels with different carbon content were prepared. Neutron diffraction measurements were performed using beamline 19 TAKUMI, a pulsed-neutron TOF diffractometer in J-PARC. Detail results will be shown and discussed during presentation.
