- Abstract:
- 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.
