摘要
本文定量分析了合金相的溶解析出规律 ,探讨了不同热处理制度对合金组织和力学性能的影响。结果表明 :合金中γ’相和碳化物相的析出峰分别在 70 0℃和 85 0℃左右 ,其大量溶解进入固溶体的温度分别为大于 10 2 0℃和大于 10 0 0℃ ,合金较为合适的热处理制度为 10 80℃× 8小时空冷 (或水冷 ) + 70 0℃× 16小时空冷或 10 80℃× 8小时空冷 (或水冷 ) + 85 0℃× 2 4小时空冷 + 70 0℃× 16小时空冷。
The rule of phases soluttion precipiation has been quantitatively analyzed.The influence of different methods of heat treatment on the structure and mechanical properties of GH80A alloy has been studied.The test results showed that precipitation peaks of γ’phase and carbides in alloy had occurred separately at abaut 700℃ and 850℃,and a great quantities of them had been soluted into solid solution over 1020℃ and 1000℃ respectively.The preferred method of heat treatment for GH80A alloy is shown to be 1080℃×8h air or water cooling+700℃×16h air cooling or 1080℃×8h air or water cooling+850℃×24h air cooling+700℃×16h air cooling
