The Experimental Study of 15CrMo Steel Fatigue Performance

Abstract:

15CrMo steel is widely used in engineering. In order to evaluate the fatigue performance of 15CrMo, axial loading for 15CrMo specimen has applied by high frequency fatigue testing machine under stress ratio R=0.1 at room temperature, the linear S-N relationship has obtained by grouping fatigue test, the fatigue limit has obtained and compared by two different fatigue limit analysis method. The consequences of this test could provide a theoretical support for the use of 15CrMo in engineering and the research of fatigue limit theory.
