摘要：
An self-designed automatic liquor cycling unit for fatigue testing was introduced, and the experimental research of corrosion-fatigue properties of Ti-75 titanium alloy was carried out. The fatigue limits of 1×107 cycles determined in air and in 3.5wt% NaCl aqueous solution at room temperature are 392 MP and 431 MPa respectively. The results indicate that the corrosion-fatigue properties of Ti-75 alloy increase by a factor of 29% in air and 26% in 3.5wt% NaCl aqueous solution, as compared with TA5 alloy. The improvements of the properties shown above are related to the microstructure of Ti-75 alloy.
