Abstract
This work aims at developing an energy-efficient process for production of high strength hot-rolled quenching and partitioning (Q&P) steel. A novel processing strategy involving quenching above martensite start temperature (Ms) in combination with dynamic carbon partitioning is first proposed for hot-rolled Q&P process. The alloy 0.25C-3Mn-2Al (wt%) was intentionally designed to low interface mobility during slow cooling in bainite range and thus controlled partial bainite transformation. Finally, multi-phases containing ferrite, martensite and nano-sized retained austenite were obtained and an improved mechanical property can be achieved with tensile strength ∼1096 MPa and uniform elongation ∼16%. This work breaks the Q&P constraint with quenching temperature below Ms and provides an easy-industrialized processing route.
