Abstract

Abstract

In this paper, the multi-directional forging test of Ti80 titanium alloy for automobile manufacturing was carried out, and the microstructure, room temperature mechanical properties and wear resistance of the alloy samples were tested and analyzed. The results show that the forging temperature and the forging pass have obvious effects on the microstructure, mechanical properties and wear resistance of the specimen. With the increase of the forging temperature from 880 ℃ to 960 ℃ and the forging pass from 2 to 8, the microstructure of the multi-directional forging specimen is refined first and then coarsened, and the mechanical properties and wear resistance are increased first and then decreased. When the forging temperature is at 920 ℃ and the forging pass is at 5, the grain size of the sample is the smallest, the second phase is in continuous network distribution, the mechanical properties and wear resistance of the sample are the best, the tensile strength and yield strength of the sample are 976 MPa and 892 MPa respectively, and the wear volume is only 7×10⁻³ mm³ after 15 minutes of wear.
