In situ neutron diffraction analysis of microstructural evolution-dependent stress response in austenitic stainless steel under cyclic plastic deformation

•Stress partitioning in the austenite and deformation-induced martensite was studied.•The phase stress in the austenite is related to its dislocation density.•The stress in the martensite relies on the assumed stress and stress in the austenite.•The martensitic transformation causes hydrostatic compressive residual stress.•The equivalent stress in the martensite at peak tensile loads is fairly high (1 GPa).
