| 摘 要： | 采用OM、SEM、XRD、维氏硬度以及力学性能测试等方法，研究了固溶时效处理对TC6合金显微组织、相结构以及力学性能的影响。结果表明：TC6合金经过900 ℃固溶处理后，合金由片层α相、针状马氏体α′相以及β相组成；而经过1000 ℃固溶处理后，合金主要由针状α′马氏体相和β相组成。对不同固溶温度下的合金样品进行时效处理，针状α′马氏体相完全分解为α相和β相。并且随着时效温度升高，β相的相对含量逐渐增大。通过对比，TC6合金经过900 ℃固溶后在500 ℃下进行时效处理后综合力学性能达到最佳，此时的抗压强度和屈服强度为2000 MPa、1061 MPa，硬度值为499 HV0.2。

| Abstract: | Effect of solid solution and aging treatment on microstructure, phase structure and mechanical properties of TC6 alloy was investigated via optical microscope (OM), scanning electron microscope (SEM), X-ray diffraction (XRD), Vickers hardness tester and mechanical properties testing system. The results show that the TC6 alloy is mainly composed of lamellar α phase, needle-like martensite α′ phase and β phase after solution treatment at 900 ℃. However, after solution treatment at 1000 ℃, the alloy is mainly composed of needle-like martensite α′ phase and β phase. During the aging process at different temperatures, the α′ martensite phase formed under water quenching is decomposed and transformed into α and β phases completely. Also, with the aging temperature increasing, the relative content of β phase increases gradually. By comparison, the overall mechanical properties of the TC6 alloy after solution treatment at 900 ℃ and aging at 500 ℃ are the optimal, with the compressive strength and yield strength being 2000 MPa and 1061 MPa respectively, and the hardness value being 499 HV0.2. |
