Especially the effects of strain rate, strain amplitude and polarization were researched. The results showed that the crack initiation life decreased with the decrease in strain rate and the increase in strain amplitude. The anodic and high cathodic polarization decreased greatly the crack initiation life. The crack initiation life under the cathodic protection condition was nearly same as that in air. Crack foimed mainly in the soft ferritic phase, and then connected together through pearlite. The intensive anodic dissolution cleared the surface deformation morpohology. The cathodic hydrogen reduction induced the small crack formation at the deformed surface.
