The extensive use of liquid-oxygen and liquid-hydrogen propellants in missiles and spacecraft has placed an increasing demand upon the metallurgist to provide engineering materials for structural applications at cryogenic temperatures. The selection of a material for structural use at cryogenic temperatures is primarily dependent upon the material’s strength-to-density ratio and resistance to brittle fracture. Alloys with high strength-to-density ratios are required in order to minimize weight and meet design requirements of flight articles. Also of prime importance is the material’s toughness, or resistance to brittle fracture, under conditions of high stress, impact, repeated loading, and extreme low temperatures.
