摘要

The microstructural evolution, mechanical properties and oxidation behavior of Ti-6Al-2Zr-1Mo-1V-based alloys with 0-3.8wt% Sc additions have been investigated. The Sc addition decreased the β-trans temperature and refined the microstructure of the alloy. Sc partitioned into the α-phase and was depleted in the β-phase with increasing Sc content. This resulted in the formation of a small amount of Sc₂O₃ particles in the high Sc-containing alloys. The Sc addition improved the yield strength at both room temperature and high temperature, whereas refined the oxide products and decreased the oxidation resistance of the base alloy. The oxidation behavior with Sc addition was discussed.
