Abstract The effect of refined cementite on the microstructure, conventional mechanical properties, wear resistance and contact fatigue properties of GCr15Si1Mo bearing steel was studied. Through controlling the heat treatment process, the size of cementite and bainite ferrite lath in the microstructure was refined from 0.49 to 0.20 μm, and 66 to 41 nm, respectively, and the distribution density of cementite also increased. Then through SEM, TEM, XRD, hardness, impact, wear and rolling contact fatigue tests, the macroscopic properties and microstructure of the material were obtained. The results showed that after refining cementite, the wear resistance and rolling contact fatigue property of the specimen were better than that produced by the conventional process, while the toughness was worse. The research proved that the finer cementite can have a certain influence on the microstructure, conventional mechanical properties, wear resistance and rolling contact fatigue property of the bearing steel, which provided support for the later research on the control of cementite in bearing steel.
