采用光學顯微觀察、力學性能測試、疲勞性能測試和掃描電鏡斷口分析等手段,研究不同鍛造工藝和熱處理對TC11鈦合金鍛件組織和性能的影響。結果表明:高溫均勻化處理適用于TC11鈦合金。經過高溫均勻化鍛后,鍛造態態組織能為鍛后熱處理提供了良好的基礎,有益于改善TC11鈦合金的綜合性能。
The effects of different forging processes and heat treatments on microstructures and properties of TC11 titanium alloy were investigated by means of optical microscope observation, mechanical property test, fatigue property test and scanning electric microscope fractography analysis. The results show that the high temperature homogenizing forging is suitable for TC11 titanium alloy. After high temperature homogenizing forging, the as-forged microstructure can lay a good basis to the next heat treatment, which is beneficial to improving comprehensive properties of TC11 titanium alloy.
