| 摘 要： | 采用喷射沉积及原位反应喷射沉积方法制备7093铝合金及7093+TiC铝合金,研究试验合金420℃热挤压及不同固溶处理后的微观组织和力学性能。探索原位TiC颗粒对喷射沉积7093铝合金组织的影响。结果表明,原位TiC颗粒能够提高喷射沉积7093铝合金的再结晶温度10℃,当固溶温度达到490℃时,7093+TiC铝合金中的富Cu颗粒基本溶解,但并未出现过烧现象。采用450℃×3h+480℃×3h+120℃×24h的制度处理后,7093+TiC铝合金的抗拉强度达754 MPa,伸长率达7.1%。

| Abstract: | 7093 Al alloy was prepared with the spray-forming method and 7093 + TiC Al alloy composite material was prepared with a insitu reactive spray-deposition process. Mierostrueture and mechanical properties of the alloys treated with 420 ℃ hot extrusion and different solid solution were investigated. The effects of in-situ TiC particles on microstrueture of the spray-deposited 7093 Al alloy was examined. The results show that the recrystallization temperature of 7093 + TiC Al alloy is higher 10 ℃ than that of 7093 Al alloy. When the temperature of solid solution treatment is up to 490 ℃ , Cu-rich particles in 7093 + TiC Al alloy are dissolved completely, and over-burning phenomenon is not observed. After heat treatment of 450 ℃×3h +480 ℃×3h + 120 ℃×24h,the ultimate tensile strength of 7093 + TiC Al alloy is 754 MPa and its elongation reaches 7.1%. |
