Abstract Scope Fundamental mechanisms responsible for the cracking phenomenon in advanced high strength steel alloys subjected to deep-drawing processes have been investigated using in-situ neutron diffraction and synchrotron x-ray diffraction. Despite high hardening rate and tensile ductility, the transformation-induced plasticity (TRIP) steels are susceptible to cracking mainly due to residual-stress concentration. In this study, a lean duplex TRIP steel with superior resistance to cracking has been developed by manipulating the residual-stress partitioning and plastic anisotropy. The evolutions of lattice strain, texture, and the martensitic transformation kinetics were studied to understand the constitutive behaviors of TRIP steel and lean duplex TRIP steel during uniaxial deformation. Subsequently, distributions of residual stresses and martensite phase fraction were mapped in deep-drawn steel cups. By investigating the effects of the martensitic transformation, duplex microstructure, and texture on the residual-stress partitioning and plastic anisotropy, their influences on the stress concentration and cracking behavior is elucidated.
