Abstract：

Abstract: In order to explore the service performance of TA15 titanium alloy, the tensile and wear properties of TA15 titanium alloy at a wide area temperature from room temperature to 800 ℃ were systematically analyzed. Then, the microstructure and wear morphology of the alloy were analyzed. The experimental results show that the tensile strength of TA15 titanium alloy significantly decreases with the increasing of temperature at the loading speed of 1 mm·min-1 , and all test samples at all temperatures exhibit the ductile fracture. Especially above 600 ℃, TA15 titanium alloy exhibits extremely high ductility and plasticity. At 600 ℃, TA15 titanium alloy not only has high tensile strength, but also presents the lowest friction factor, making it an ideal material for high-temperature service environments. The influence laws of different temperatures on the tensile fracture surface, wear mechanisms and microstructure of TA15 titanium alloy are obtained, contributing the reference to the study of the high-temperature properties for TA15 titanium alloy.
