摘要

研究了固溶温度和冷却速率对TC11钛合金显微组织、室温和高温力学性能的影响。结果表明

随着固溶温度、冷却速率提高

TC11钛合金中的初生α相含量明显降低

随着冷却速率提高

次生α相细小且弥散分布。在相同的固溶温度下

随着冷却速率提高

合金的室温强度以及500℃高温强度明显提高

塑性明显下降。在950℃水冷处理再进行时效处理后合金的强度最高

可达1 300 MPa以上。

Abstract

The effects of solution temperature and cooling rate on the microstructure

ambient and elevated mechanical properties of TC11 titanium alloy were investigated. The results indicate that with the increase of solution temperature and cooling rate

the content of primary α phase in TC11 titanium alloy is decreased obviously

and the secondary α phase becomes finer with more dispersed distribution. At the same solution temperature

the room temperature strength and 500 ℃ high temperature strength of the alloy are increased

and the plasticity is decreased significantly with the increase of cooling rate. After 950 ℃ water cooling treatment and aging

the strength of the alloy reaches over 1 300 MPa.
