摘要： A process for improving 6XXX alloys, such as 6013, preferably includes heating, hot rolling, inter-rolling thermal treatment at a very high temperature such as 1020 °F or more, again hot rolling (with or without subsequent continuous hot rolling or cold rolling or both), solution heat treating and artificial aging. The initial heating, inter-rolling, thermal treatment and solution treatment, especially the latter two, are carried out at very high temperatures such as 1030 °F. Each aforesaid hot rolling stage produces substantial metal thickness reduction. The improved sheet or plate product has a substantially reduced occurrence of reduced density features revealed in scanning electron microscope examination at 500X and exhibits improved (reduced) fatigue crack growth rate providing an advantage in aerospace applications such as fuselage skin, especially fuselage belly skin.
摘要翻译：改进6XXX合金（例如6013）的方法优选包括加热，热轧，在非常高的温度（如1020°F或更高）下进行的热轧，再次热轧（连续或不用连续的热轧或冷轧或两者），溶解热处理和人造时效。最初的加热，交联，热处理和固溶处理，特别是后两种，在非常高的温度例如1030°F下进行。每个上述热轧阶段都产生大量的金属厚度的减少。改进的片材或板材产品在500X扫描电子显微镜检查中显示的减少的密度特征显着降低，并且显示改善的（降低的）疲劳裂纹扩展速率，这在航空航天应用如机身皮肤，特别是机身腹部皮肤中提供优点。
