| 中文摘要: |
| 2024-O铝型材成形后，需要进行热处理才能达到最终的T62状态.合适的热处理工艺参数会得到性能较理想的最终型材，但是热处理工艺的最佳参数对热处理的工艺控制要求很高，因此很难确定.首先经由2024-O铝型材热处理工艺试验，系统地研究了固溶处理制度、淬火和人工时效制度等工艺因素对合金显微组织和力学性能的影响.其次，采用透射电子显微镜（TEM）和X射线衍射仪（XRD），在微观上研究不同制度下，型材微结构的变化与增强相的析出.最后确定了实验室条件下2024-O状态铝型材T62热处理的最佳工艺参数，即（490~505）℃×（20~40）min+（185~195）℃×（8~14）h.在该制度下，型材合金具备较优的综合性能. |

| In order to get relatively ideal property of T62 state on 2024-O aluminum alloy,it needs to be heat treatment with appropriate parameters after molded.It is not easy to get the optimal parameters from the heat treatment which is still very challenge as it require highly control.In this study,2024-O aluminum alloy was systematically studied on microstructure and mechanical properties under various processing,such as solution temperature,holding time,quenching,and artificial aging system.The microstructure has been changed and the precipitate phase has been enhanced where observed by using TEM and XED.Finally,the alloy with better comprehensive performance was obtained by the confirmed parameters of (490-505)℃/(20-40)min+(185-195)℃/(8-14)h,which is the most suitable parameter for 2024-O aluminum alloy with T62 state inlaboratory condition. |
