| Abstract: |
The specimens of a high carbon chromium steel were quenched and tempered at 150A degrees C, 180A degrees C and 300A degrees C. Such specimens were tested via rotating bending and a push-pull type of axial loading to investigate the influences of loading condition on the behaviour of very-high-cycle fatigue (VHCF). Experimental results show the different influences of inclusion size on the fatigue life for the two loading conditions. Predominant factors and mechanism for the fine-granular-area (FGA) of crack origin were discussed. In addition, a reliability analysis based on a modified Tanaka-Mura model was carried out to evaluate the sensitivity of inclusion size, stress, and Delta K (FGA) to the life of VHCF crack initiation.
