  • For a conventional low alloyed steel, two different initial microstructures were achieved by conventional hot rolling and high-temperature annealing followed by cold rolling. The effects of the initial microstructures on the microstructure and mechanical properties after austenitization and quenching were investigated. The results indicate that the quenched microstructure of the conventional hot-rolled sample is relatively coarse, while the high-temperature annealing followed by cold rolling, which introduces more grain boundaries, a higher density of cementite, VC, and dislocation defects before quenching, can significantly refine the quenched microstructure. Both hot-rolled and cold-rolled samples achieve a high strength-ductility balance, but the cold-rolled sample, with its more refined microstructure, exhibits superior strength and ductility. The cold-rolled sample achieves ultra-high tensile strength of 2384 MPa and extraordinary total elongation of 14.0%, with product of strength and elongation reaching 33.4 GPa·%.
