研究了损伤容限TC 4-DT钛合金经不同热处理后的显微组织和力学性能。研究了初生α相体积分数和片层组织形貌对合金拉伸性能和断裂韧性的影响。进行了静态拉伸、断裂韧性试验和显微组织研究。结果表明，热处理可以调节合金的组织特征，冷却速度和时效条件对等轴α相含量、β相晶粒尺寸和片层α相厚度等组织参数有显著影响，从而对合金的性能产生显着影响。(c)2012爱思唯尔有限公司版权所有。
This paper presents the results on the microstructure and mechanical properties of damage tolerance TC4-DT titanium alloy after different heat treatments. The influence of volume fraction of primary alpha-phase and the morphology of lamellar microstructure on the tensile properties and fracture toughness of the alloy was studied. Static tensile, fracture toughness tests and microstructure investigations were performed. The result shows that heat-treatment can adjust the microstructure feature, and cooling rate and aging conditions have remarkable effect on the microstructure parameters, such as the content of equiaxed alpha, dimension of beta grains and thickness of lamellar alpha, which has a significant effect on the properties of the alloys tested.
