SELECTION OF MATERIALS FOR CRYOGENIC APPLICATIONS IN MISSILES AND AEROSPACE VEHICLES
Abstract
A number of high strength structural sheet alloys, plastics, and thermal insulation materials were subjected to a variety of mechanical and physical property tests over the temperature range of +78 F down to -423 F. Of the sheet alloys tested, desirable combinations of high strength, high resistance to brittle fracture, and good weldability are exhibited by the following: severely cold rolled stainless steels such as Types 301, 304, and 310 (although Type 301 appears marginal at liquid H temperatures), Ti A110-AT, Al alloy 5052-H38, and age hardened K-Monel. 20% cold worked Haynes 25 alloy and 40% cold rolled Hastelloy B alloy exhibit good strength and brittle fracture resistant properties at temperatures down to -423 F. Al alloy 6061-T6 has good toughness down to -320 F but exhibits moderate notch sensitivity at -423 F. The high strength Al alloys of the 2000 and 7000 series are very notch sensitive at -320 F and at -423 F. (Author)
