Quenching and partitioning (Q&P) process is an effective approach to control the amount and stability of retained austenite. Our previous study confirmed that carbon partitioning and isothermal transformation simultaneously occurred below martensitic transformation starting (Ms) temperature. In order to deepen the understanding on controlling microstructures through Q&P processes, the effect of ausforming on phase transformation and carbon partitioning during the Q&P process were investigated by the use of in-situ neutron diffraction in the present study.
