| 摘要 | Superior strength-ductility synergy of 1045 carbon steel produced by aluminothermic reaction casting method was obtained through large deformation rolling at ambient temperature and subsequent annealing, meanwhile, a heterogeneous composite structure was fabricated. The heterogeneous structural 1045 carbon steel consists of soft microcrystalline/ultrafine grained (UFG) ferrite and hard cementite nanoparticles. The outstanding strength-ductility synergy was primarily attributed to the microstructure characteristics about the soft/hard interfaces of heterogeneous composite structure. The strength was improved due to the second phase reinforcement of hard cementite nanoparticles and decreasing of ferrite grain size, meanwhile, the back stress hardening capacity of soft/hard phase also resulted in the high strength. And the favorable ductility was ascribed to the generation of geometrically necessary dislocations (GNDs) around soft/hard interfaces, which resulted in the high work hardening capability of heterogeneous structural 1045 carbon steel. It is remarkable that tensile strength (similar to 1190 MPa) and high yield strength (similar to 1118 MPa) and good ductility (similar to 10.6%) can be simultaneously acquired for the cold rolled 1045 steel after annealing at 673 K for 1 h.
