Testing Techniques and Evaluation of Materials for Use at Liquid Hydrogen Temperature

Facilities for performing mechanical property testing and structural component testing at cryogenic temperatures, particularly liquid hydrogen temperature (−423 F), are described. Preliminary uniaxial test results obtained in the mechanical property program indicate that the aluminum alloys 2014-T6, 6061-T6, 5456-H24, and 2219-T81 should behave satisfactorily in liquid hydrogen service. Unnotched, notched, and weld properties are given. Biaxially loaded structural component tests of parent metal showed good agreement with uniaxial tests. The results of welded specimen testing, however, showed a significant decrease in strength compared to uniaxial test results, due to residual stresses. Biaxial stress-strain curves are given for several lightweight metals.
