High strength Ti alloy material having improved workability and process for producing the same |
| 摘要 |
Herein disclosed are a high-strength Ti alloy material having improved workability which contains 2-5% Al, 5-12% V and 0.5-8% Mo (the percents being on a weight basis) and which satisfies the relation: 14%</=1.5x(V content)+(Mo content)</=21%, with the balance being Ti and incidental impurities, and a process for producing such high -strength Ti alloy material. The process comprises: preparing a Ti alloy ingot having the above specified composition; hot working the ingot at a temperature wihtin the range of 600 DEG -950 DEG C.; subjecting the work to solid solution treatment at a temperature in the range of 700 DEG -800 DEG C.; and age-hardening the work at a temperatrue between 300 DEG and 600 DEG C. The reesulting Ti alloy material is suitable for use in the fabrication of parts of aircraft where high specific strength and heat resistance are required.
