Abstract: A method of producing an AA7000 series aluminum alloy wrought product or plate includes a two step solution heat treating sequence wherein the aluminum plate is subjected to a first solution heat treatment at a first elevated temperature or temperatures for a first period of time, followed by a second solution heat treatment at a lower temperature or temperatures for a second period of time. The two step solution heat treating sequence results in vastly improved exfoliation corrosion resistance in the final aluminum wrought or plate product. An improved process for making aluminum alloy products in the T7751 Temper also is disclosed.

Abstract translation: 一种生产AA7000系列铝合金锻造产品或板的方法包括两步溶解热处理顺序，其中铝板在第一升高的温度或温度下进行第一固溶热处理第一时间段，接着是 在较低的温度或温度下进行第二次固化热处理第二个时间段。 两步溶解热处理程序导致最终的铝加工或板材产品的抗剥落腐蚀性大大提高。 还公开了在T7751 Temper中制造铝合金产品的改进方法。
