ABSTRACT:
A method of producing an aluminum alloy having superplastic properties, including the steps of: heating the aluminum alloy; hot rolling to an exit temperature ranging from about 650.degree. to 70.degree. F.; and cold rolling to a gauge corresponding to a percentage of cold work selected from among those falling within the zone defined by the lines joining the points of A (475.degree. F., 10%), B (650.degree. F., 99%), C (70.degree. F., 99%) and D (70.degree. F., 10%), shown in FIG. 2, showing the relationship between the temperature range of the hot rolling exit temperature and the percent of cold work.
