固溶处理对Ti65高温钛合金组织与性能的影响Effects of solution treatment on microstructures and properties of Ti65 high-temperature titanium alloy
研究Ti65高温钛合金的固溶处理工艺，分析不同固溶处理的Ti65高温钛合金的金相组织，测试Ti65高温钛合金的力学性能。结果表明：随着固溶温度的提高，Ti65高温钛合金初生α相的尺寸与含量减少，拉伸性能降低，蠕变性能提高；随冷却速率的提高，合金次生α相尺寸变小，长宽比增大，拉伸强度和蠕变性能提高，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.
