AbstractThis study provides an effective surface processing technology to increase the local mechanical properties of medium carbon steel castings. Ultrafine dual-phase structure of the ferrite and the martensite was obtained in the processed zone with a depth of 1 mm via submerged friction stir processing (FSP). Significantly enhanced yield strength (YS) of 2070 MPa was achieved in the FSP steel compared to that of the base material (BM) with a relatively low YS of 590 MPa, but a low uniform elongation (UE) of 3.0% was achieved compared to that of the BM (9.4%). After annealing, obvious carbide precipitation was observed in the original quenched martensite phases. Therefore, good strength-ductility synergies with high YS of 1020 MPa and 925 MPa, and acceptable UE of 5.9% and 9.3% were achieved in the FSP steel after annealed for 2 h at 500 degrees C and 600 degrees C, respectively.
