, and the fatigue life is longer than 1×107 cycle. Under the conditions of Kt=1, stress ratio R=0.1 and stress intensity factor amplitude △K=30 MPa·m1/2, the fatigue crack growth rate da/dN along the longitudinal and transverse direction are 2.73×10-3-4.41×10-3 mm/cycle and 5.76×10-3-8.22×10-3 mm/cycle, respectively. The fatigue cracks mainly initiate on the non-metallic inclusions containing O, Na, Cl......
