| 摘 要： | 研究了化学成分和热处理工艺对TA5合金棒材力学性能的影响。结果表明，增加铝、氧、氮元素的含量，提高铝强度当量，TA5合金棒材强度显著提高，塑性略有降低。在700~800℃范围内升高退火温度，TA5合金棒材的强度降低，塑性升高；在740~780℃退火时，其强度和塑性匹配最佳。与空冷相比，采用炉冷+空冷的冷却方式时，TA5合金棒材的强度降低，塑性显著升高。

| Abstract: | The effects of chemical composition and heat treatment process on mechanical properties of TA5 alloy bars were investigated. The results showed that the strength of TA5 alloy bars increased obviously while the plasticity declined slightly by increasing the content of aluminum, oxygen and nitrogen elements to enhance aluminum equivalence. With increase of annealing temperature between 700℃ and 800℃, the strength declined and the plasticity rose. The strength and plasticity of TA5 alloy bars could best match when heat treatment temperature was between 740℃ and 780℃. Compared with air cooling, the strength of TA5 alloy bars declined and the plasticity rose evidently when combination of furnace cooling and then air cooling was adopted. |
