热处理对TA15钛合金高周疲劳性能的影响Effects of heat treatment on high cycle fatigue strength of TA15 alloy
以不同热加工工艺获得的TA15合金d18 mm规格棒材为例，研究氧含量的变化和热处理制度以及初生α相对其高周疲劳强度的影响。结果表明：热处理制度和氧含量的变化对TA15合金高周疲劳性能的影响不大，初生α相对高周疲劳性能的影响显著，当初生α相的含量由15%~20%提高到33%~40%时，疲劳强度可以提高25%左右。
The effects of content of O element，heat treatment and α phase of TA15 alloys on high cycle fatigue strength of TA15 alloy bar with d18 mm were studied. The results show that the effects of content of O element and heat treatment on high cycle fatigue strength of TA15 alloy are limit. But α phase of TA15 alloy bar has a remarkable effect on high cycle fatigue strength. The high cycle fatigue strength of TA15 alloy bar would be improved by 25% with increasing primary α phase content from 15%−20% to 33%−40%.
