研究了Ti-26合金在不同固溶温度和固溶时间条件下β晶粒的长大规律,并且计算了该合金在775～880 ℃范围内,保温1 h时,β晶粒的长大激活能Qm和在820 ℃保温0.5～4 h的生长指数n,分析了影响β晶粒的长大激活能Qm和生长指数n的主要原因.研究表明,Ti-26合金在β相区不同温度保温时,β晶粒的长大过程受Ti元素控制;合金在820 ℃(Tβ+45 ℃)固溶时,晶粒生长指数n仅为0.24是由于固溶原子落后于β晶界的移动而形成拖曳造成的,然而当固溶温度超过820 ℃时,β晶界的移动可以摆脱溶质原子的束缚.

The growth law of Ti-26 alloy under different solution temperature and solution time conditions β was studied, and the growth activation energy Qm of the β grain and the growth index n of 775.880~1 h at 820 °C were calculated when the alloy was kept warm for 0 h in the range of 5~4 °C, and the main reasons affecting the growth activation energy Qm and growth index n of the β grain were analyzed. The results show that when Ti-26 alloy is insulated at different temperatures in the β phase, the growth process of the β grain is controlled by Ti. When the alloy is soluble at 820 °C (Tβ+45 °C), the grain growth index n is only 0.24, which is caused by the drag of the solid solution atoms lagging behind the movement of the β grain boundary, but when the solution temperature exceeds 820 °C, the movement of the β grain boundary can get rid of the shackles of solute atoms.
