影响铝合金固溶保温时间的多因素相关规律

提出了确定铝合金固溶保温时间的相关强化技术。该技术充分考虑了影响铝合金性能的诸因素以及这些因素之间的相互影响和相互补偿关系，克服了传统的由单一厚度因素确定固溶保温时间的局限性。实践证明：与目前最先进的美国军用标准ＭＩＬＨ６０８８Ｇ相比，用该相关强化技术确定固溶保温时间可使产品力学性能提高１０％～４０％，大幅度地提高塑性指标，减小各向异性，更有效地控制粗晶和粗晶环。

DISCIPLINES OF MULTIPLE FACTORS AFFECTING SOLUTION TREATING OF ALUMINUM ALLOY

A multiple factor related strengthening technology on aluminum alloy solution treating is put forward. It has fully considered various factors which influence the properties of aluminum alloy, as well as the interaction and inter compensation among them. It eliminates the one sidedness of the traditional method which determines the holding time of solution only by the thickness. Compared to the American Military Standard MIL H 6088G which is considered as the most advanced one by now, the multiple factor related strengthening technology can improve the mechanical properties of aluminum alloy products by 10 to 40 percent, improve the plastic index obviously, reduce the anisotropy, and controll the coarse grain and the coarse grain annulus effectively.
