《Effect of main inclusions on crack initiation in bearing steel in the very high cycle fatigue regime》
wt%
The material used in this study was the high carbon–chromium-bearing steel GCr15.The chemical composition of the investigated steel is shown in Table 1.The main deoxidant used in the smelting of this steel was Al，and the steel was prepared as round bars with a diameter of 35 mm after hot rolling.Heat treatment procedures consisted of annealing，quenching，and tempering.The quenching condition was vacuum oil quenching after holding for 20 min at835°C.The tempering condition was holding for 120 min at180°C.The microstructure of the steel was identified as martensite，as shown in Fig.1.
