固溶處理對Ti65高溫鈦合金組織與性能的影響Effects of solution treatment on microstructures and properties of Ti65 high-temperature titanium alloy
研究Ti65高溫鈦合金的固溶處理工藝，分析不同固溶處理的Ti65高溫鈦合金的金相組織，測試Ti65高溫鈦合金的力學性能。結果表明：隨著固溶溫度的提高，Ti65高溫鈦合金初生α相的尺寸與含量減少，拉伸性能降低，蠕變性能提高；隨冷卻速率的提高，合金次生α相尺寸變小，長寬比增大，拉伸強度和蠕變性能提高，塑性和持久性能降低。
The solution treatment process of Ti65 high-temperature tianium alloy was studied. The microstructure of Ti65 alloy was analyzed by optical mircoscopy. The mechanical properties of the alloy were tested. The results show that, with the solution temperature increasing, both the size and content of the primary α phase of the alloy and the tensile properties decrease, but the creep properties improve. With the increase of cooling rate, the size of secondary α phase, plasticity and stress rupture life of the alloy decrease, but the tensile properties improve.
