Abstract

Currently, large amounts of liquefied gases such as oxygen and hydrogen are used for space vehicle propellants. Aluminum alloy structural components of increasing design complexity, which are in contact with these liquids, must often withstand high stresses at extremely low temperatures. Aluminum forgings and welded structures, which are costly and usually require extensive machining, are used in many instances where a casting would be ideal. Suitable castings must have high strength and toughness and must be compatible with the adjoining aluminum alloy structure. A commercial casting alloy, having optimum properties for these requirements, has not been available.
