The quantitative formulas of fatigue life were obtained by regression analysis method, and the
fatigue fracture mechanism was analyzed. The results show that a linear correlation was found
between fatigue life and effective stress in the double logarithmic plots. Cracks initiated from the
specimens surfaces under tension-compression loading as well as torsion loading. For the
tension-compression fatigue and the torsion fatigue specimens, the main characteristics for
cracks propagation were striations and sheares ripple marks, respectively. © (2013) Trans Tech
