后处理对ZTA5铸造钛合金材料组织及性能的影响

Influence of Treatment after casting on the Mechanical Properties and Microstructure of ZTA5 Cast Titanium Alloy Material

    摘要
  • 摘要: 本文对ZTA5铸造钛合金材料在铸造状态和不同后处理状态下的性能和微观组织进行了试验研究。试验结果表明,该合金在铸造状态下,存在一定的铸造残余拉应力,但经热处理或热等静压后,力学性能有所提高,力学性能数据分散度有所降低。

     

    Abstract: The microstructures and mechanical properties of cast titanium alloy ZTA5 under different conditions have been studied． The results show that some pull stress was existed in ZTA5 alloy castings，the properties of ZTA5 alloy castings was improved after heat treatment or HIP and the scattering degree of mechanical properties datum was reduced.
