对更轻、更省油和更高性能的汽车的需求刺激了对高强度和高成形性铝合金的研究和开发。据报道，人工时效Al-Mg-Si合金的力学性能受自然时效的影响很大。这个问题以前已经得到了广泛的研究，并提出了许多方法来将自然老化的有害影响降到最低。本文报道了一种在模拟烤漆条件下提高两种Al-Mg-Si合金强度的预时效方法。
The demand for more lightweight, fuel efficient and enhanced performance automobiles has stimulated research and development in high-strength and high formability aluminum alloys. It is reported that the mechanical properties of Al-Mg-Si alloys obtained through artificial aging are influenced significantly by the natural aging. This problem has been extensively studied previously, and many methods are suggested to minimize the detrimental effect of natural aging. This paper reports on a pre-aging method which can improve the strength of two Al-Mg-Si alloys in a simulated paint baking condition.
