Abstract
Titanium alloys, which possess high specific strength and excellent corrosion resistance, have received more and more attention, due to urgent demands of marine equipments for high-performance materials. However, application of titanium alloys is limited in our marine equipments due to absence of service performance data, our equipment design and application units are hesitated to choose materials type. In the present study, compressure creep, low cycle fatigue and stress corrosion property of TC4 ELI alloy with different microstructures were investigated. Results indicated that the basketweave microstructure possesses better compression creep behavior in comparison with duplex microstructure, the duplex microstructure possesses better low cycle fatigue property in comparison with Widmanstatten microstructure, and the Widmanstatten microstructure possesses better stress corrosion property in comparison with duplex microstructure. It can be seen that the microstructure has important effects on the service performance of titanium alloys, it should be selected according to the specific service conditions.
