This means that the residual strain in rolled alloy promoted the aging process. The influence of aging temperature on the room-temperature mechanical properties of 1〓, 2〓 and 6〓 alloys was tested and the results show that the 1〓 alloy without minor element additive is very sensitive to the aging temperature. Over-aging occurred easily when the aging temperature is somewhat higher, so it is difficult to control the aging treatment in production. The 6〓 alloy with combined Mg, Cr, Co additives showed less tendency of over-aging, the alloy can be aged in a wider temperature range and the mechanical property is stable. So the treatment process can be easily controlled.

对不同微量添加元素的1〓、2〓和6〓三种合金经热轧态时效后的室温力学性能表明，不添加微量元素的1〓合金对时效温度较敏感，温度偏高时容易产生过时效，且过时效的温度明显低于加Mg的2〓合金和同时加Mg、Cr、Co的6〓合金，这对生产过程中的工艺控制增加了难度，6〓合金的过时效倾向最小，合金可以在较宽的温度范围内进行时效，力学性能较稳定，使生产工艺较易控制。
