AbstractAn anomalous high-strain-rate softening phenomenon was demonstrated in a high-strength quenching and partitioning (Q&P) steel. It was found that the high-strain-rate softening in the Q&P steel is caused by the intrinsic carbon-dislocation interaction, rather than transformation induced plasticity effect, dislocation density difference, or adiabatic heating. The key mechanism is ascribed to the disappeared Cottrell drag force during high-strain-rate deformation, which originates from carbon-dislocation interaction and is present during quasi-static deformation.
