摘要

采用金相观察、拉伸试验等方法研究了固溶及时效制度对β21s钛合金板材显微组织及力学性能的影响。结果表明

β21s钛合金在815

45℃温度范围内固溶后

室温拉伸时合金具有较高的塑性和适中的强度

且随着固溶温度的升高

强度降低、塑性升高;时效处理后合金具有很高的强度及较好的塑性

且随着时效温度的升高

合金强度降低、塑性升高。

Abstract

The effects of heat treatment on the microstructure and mechanical properties ofβ21salloy sheets were investigated by using optical microscope and tensile tester.The results show that the alloy after solution treatment at 815

45 ℃ has a moderate strength and an excellent ductility at the room temperature

and with the increase of solution temperature

strength is decreased and plasticity is increased.After aging treatment

alloy exhibits high strength and good plasticity

and with the increase of aging temperature

the strength is decreased with the increase of plasticity.
