| 摘 要： | 研究了时效硬化型GH2696合金在不同热处理工艺下的微观组织演变及硬化行为。结果表明，随着固溶温度提高，GH2696合金基体的过饱和度增加。经1100 ℃ 2 h固溶的GH2696合金γ′相在780 ℃ 16 h时效处理时析出，导致硬度显著提高。650 ℃ 16 h低温时效处理起到补充时效硬化的作用，其HBW硬度值为350。

| Abstract: | The microstructure evolution and hardening behavior of CH2696 alloy with aging hardening by different heat treatment scheme are studied. The results show that the supersaturation of CH2696 alloy matrix increases with the increase of solid solution temperature. In 1100 ℃ 2 h solution-treated CH2696 alloy the γ′phase precipitates adequately in 780 ℃ 16 h aging process, and the hardness increases significantly. The low temperature at 650 ℃ 16 h aging treatment plays the role of supplementary aging, it HBW hardness number is 350. |
