摘要
研究了Ti-26合金经不同变形量变形后,在β相区和α+β相区分别固溶、时效的力学性能和显微组织的变化。研究发现,Ti-26合金经80%变形后,经730℃×30min+500℃×10h固溶时效的综合力学性能最好;变形量为50%￣80%时,随变形量的增加,强度变化不大,塑性得到明显提高;固溶时效后的组织为β基体和基体上弥散分布的短棒状α相。
The microstructure and the properties changes of Ti-26 alloy were studied during different deformation and solution and aging treatment by TEM, SEM and X-Ray diffraction analysis. The results indicate that good combination of strength and plasticity can be obtained when the deformation amount is 80% in Ti-26 alloy after 730 ℃×30min＋500 ℃×10hAC. The strength has little change and the plasticity improves with the deformation increasing. The microstructure of Ti-26 alloy mainly consists of β phase, short-rod α phase which precipitates dispersedly after the solution-aged.
