摘要： A weld filler wire chemistry has been developed for fusion welding 2195 aluminum-lithium. The weld filler wire chemistry is an aluminum-copper based alloy containing high additions of titanium and zirconium. The additions of titanium and zirconium reduce the crack susceptibility of aluminum alloy welds while producing good weld mechanical properties. The addition of silver further improves the weld properties of the weld filler wire. The reduced weld crack susceptibility enhances the repair weldability, including when planishing is required.

摘要： Strength anisotropy of aluminum-lithium alloy wrought products is reduced by subjecting these types of alloys to improved T8 temper practice. The wrought product, after solution heat treating and quenching, is subjected to a combination of cold rolling and stretching steps prior to aging. The cold rolling can range between 1 and 20% reduction with the stretching step ranging between 0.5-10%. The cold rolling step may be performed in one or a multiple of passes. When multiple passes are used, the cold rolling may be done in different directions to further enhance reductions in strength anisotropy for these types of alloys. An aluminum-lithium alloy wrought product subjected to the improved T8 temper practice has an increased minimum tensile yield stress throughout its thickness and in various directions to facilitate commercial application of the product in high strength applications.

摘要： 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.
