本文研究了热处理工艺对Ti_3Al基合金Ti-25Al-10Nb-3V-1Mo(at％)(简称TD2)的室温和700℃拉伸性能的影响,采用光学金相,SEM和TEM观察其组织、断口特征、位错形貌。结果表明,通过调整热处理参数,可以在一定程度上改变合金的组织,从而改善合金性能。
The effects of heat treatment on the tensile properties of Ti 3 Al-based Ti-25Al-10Nb-3V-1Mo (at%) (TD2) at room temperature and 700 ℃ were investigated. The microstructure, Features, dislocation morphology. The results show that by adjusting the parameters of heat treatment, the microstructure of the alloy can be changed to a certain extent to improve the properties of the alloy.
