摘要
对6111铝合金的铸锭进行均匀化、热轧、退火、冷轧及固溶处理后,研究了其合金自然时效时及人工时效过程中硬度随时间的变化规律。研究表明,该合金具有一定的自然时效倾向,人工时效具有明显的回归现象。在人工时效前的预处理能明显增加人工时效时的硬化速度,提高烤漆硬化能力。
After casting, homogenizing, hot rolling, annealing, cold roiling and solution treating, the hardness variation of 6111 aluminum alloy during natural ageing and artificial ageing was investigated. The results show that 6111 aluminum alloy exhibits the tendency to natural aging to some extent and a reversion behavior in early stage of artificial aging. The pre-aging treatment before final aging increases the speed of agehardening or the paint bake hardening response of 6111 aluminum alloy.
