| Abstract: | Fatigue crack propagation of materials is one of the important fields in material study. This paper reviewed the effect of microstructure,temperature,erosion,stress ratio and frequency on fatigue crack propagation and showed the "plastic passivation model" and "crack closure effect" are the problems in debating. The common method and theory model were summarized and the research contents and results were introduced briefly. |

| Keywords: | fatigue crack propagation rate stress ratio titanium alloys |
