ABSTRACT:
Disclosed is a method of producing an unrecrystallized Al-Zn-Mg thin gauge flat rolled product, e.g., plate or sheet, having improved levels of strength and fracture toughness. The method comprises the steps of providing a body of a Zn-Mg containing aluminum base alloy, heating and hot working the body to a first product. This is followed by reheating, cooling and heat treating the first product prior to further working it to a thin gauge, unrecrystallized plate or sheet product, for example.
