摘要

Spacecraft cryogenic fuel tankage made from superplastic materials is a possible new application for low density aluminum alloys such as Al-Mg-Sc. Examples from this alloy system were examined for cryogenic strength and toughness. Alloys studied were received in the superplastically formable condition, in sheet form. Alloy 2219-T87 sheet was also tested for comparison, since 2219-T8X is currently used in cryogenic tankage. Five compositions of Al-Mg-Sc alloys were tested at 77 and 4 K. Alloys showed the expected increase in strength with decreasing temperature, accompanied by a general slight decrease in elongation and the Kahn tear-yield ratio toughness indicator; however, the strength-tear toughness relationship of this alloy class was as good as or better than that of 2219-T87. Correlations found between the properties, microstructure, and fracture surfaces are discussed. 8 refs., 1 fig., 3 tabs.
