固溶處理對7150鋁合金組織和力學性能的影響Effect of solution treatment on microstructures and?mechanical properties of 7150 aluminum alloy
通過OM、SEM、X射線衍射、DSC差熱分析和室溫拉伸性能測試,研究固溶處理對7150鋁合金擠壓板帶組織和力學性能的影響。結果表明:合金固溶處理溫度越高,時間越長,粗大第二相溶解越多;合金在480℃進行固溶處理時,出現過燒組織,雙級固溶處理制度沒有提高本合金開始出現過燒組織的溫度;隨著合金固溶處理時間的延長,組織出現粗化和再結晶的趨勢;本合金適合采用475 ℃,2 h的單級固溶制度,經(475 ℃,2 h) + (120 ℃,24 h)固溶?峰時效處理后,合金抗拉強度、屈服強度和伸長率分別為650 MPa、600 MPa和13.5%。
The effects of solution treatment on the microstructures and mechanical properties of 7150 aluminum alloy extrusion plate were studied by OM, SEM, XRD, DSC and room temperature tensile test. The results show that the coarse second phase dissolves more adequately when the alloy is solution treated at higher temperature for longer time. The overheated structure appears in alloys when quenched at 480 ℃, and the temperature at which overheated structure appears cannot be enhanced by two-stage solution. The trend of microstructure coarsening and recrystallization appears with prolongating the solution time. The suited solution of the alloy is single-stage solution of 475 ℃, 2 h. After solution and peak aging of (475 ℃, 2 h)+(120 ℃, 24 h), the ultimate tensile strength, yield strength and elongation are 650 MPa, 600 MPa and 13.5%, respectively.
