Experiment and Crystal Plasticity Simulation of Forming Limit of Quenching Partitioning Steel
Quenching-partitioning (QP) steel combines ultrahigh strength with good ductility due to the martensitic transformation during plastic deformation. However, the formability of the QP1180 steel remains unclear. In this paper, the ultimate strains of the QP1180 steel under different strain paths are o...

| description | Quenching-partitioning (QP) steel combines ultrahigh strength with good ductility due to the martensitic transformation during plastic deformation. However, the formability of the QP1180 steel remains unclear. In this paper, the ultimate strains of the QP1180 steel under different strain paths are obtained through Nakajima experiment. The effects of the texture evolution and phase transformation on the forming limit of QP1180 steel are analyzed by using a crystal plastic finite element model coupled with the Marciniak-Kuczynski theory (CPFEM-PT-MK). The results show that the ultimate principal strain of QP1180 steel is the lowest under the strain path ζ=0.1, and the established CPFEM-PT-MK model successfully predicts the forming limit of the QP1180 steel sheet. The texture evolutions of the constituent phases in the QP1180 steel are different under various strain paths. According to the simulation, the texture evolutions enhance the forming limit of the QP1180 steel under various strain paths. Without phase transformation, the minimum limited major strain of the QP1180 steel is located at the strain path of ζ=0, which is significantly different from that when phase transformation occurs. Furthermore, the phase transition, related to the specific strain path, does not always enhance the forming limit of the QP1180 steel. |
