Abstract
The invention provides a method for heat treating aluminum-base alloys. The method increases stress corrosion resistance after heating of the alloy to temperatures between 100.degree. C. and 150.degree. C. A dispersion strengthened aluminum-base alloy containing lithium and magnesium is shaped to form an object of substantially final form. The dispersion strengthened aluminum-base alloy is heated to a temperature between 160.degree. C. and 250.degree. C. for at least 3 hours. The heat treated object has increased stress corrosion resistance after exposure to temperatures between 100.degree. C. and 150.degree. C.
