熱處理對TA15鈦合金高周疲勞性能的影響Effects of heat treatment on high cycle fatigue strength of TA15 alloy
以不同熱加工工藝獲得的TA15合金d18 mm規格棒材為例，研究氧含量的變化和熱處理制度以及初生α相對其高周疲勞強度的影響。結果表明：熱處理制度和氧含量的變化對TA15合金高周疲勞性能的影響不大，初生α相對高周疲勞性能的影響顯著，當初生α相的含量由15%~20%提高到33%~40%時，疲勞強度可以提高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%.
