The individual phases’responses of commercial Q&P1180 steel during uniaxial tension are investigated by using the in situ neutron diffraction technique and elastic-visco-plastic self-consistent crystal plasticity method coupled with martensitic transformation crystallography theory. Stress, phase transformation, lattice strains, diffraction intensities and textures of the constituent phases are calculated and good agreement with experimental results is obtained. The phase transformation considerably enhances the flow stress and weaken diffraction intensities of the residual austenite. The orientation dependency of transformation behavior is found to be related with the transformation potency for austenite grains with different orientations. The transformation has little effect on texture evolutions for both phases.
