Abstract

One of the most important problems of the design and metallurgical engineers is the proper selection of engineering alloys for structural applications in cryogenic-fueled missiles and space vehicles. The basis for selection of a material is dependent upon many factors, the most important of which are strength, resistance to catastrophic fracture, availability, and fabricability. Materials with a high strength-to-density ratio are required for flight vehicles in order to minimize the weight and meet design requirements for payload capabilities. The alloys must possess a high degree of toughness or resistance to brittle failure in order to meet the reliability requirements. These alloys must maintain their high strengths and toughness during ground handling and flight conditions which may impose severe environments. Temperatures may range from nearly absolute zero, due to cryogenic fuels and to certain conditions in outer space, to elevated temperatures as a result of atmospheric frictional heating, engine heating, etc. Operating conditions may also include high stresses, vibration, impact and repeated loading, thermal shocks, and subjection to radiation and vacuum. The materials selected must be capable of being welded, formed, and machined in order to fabricate structural components, and must maintain their strength and toughness in the fabricated condition. Those alloys which meet the above technical requirements must be available in the sizes, forms, shapes, and quantities required, and at a cost which is not prohibitive.
