Abstract

Among the readily weldable aluminum alloys showing great promise for cryogenic applications, 2219[1,2] appears to be outstanding. In tests made recently at NASA Lewis Research Laboratories[3], the strengths of both smooth and notched specimens from 2219-T62 sheet (plain, as-welded, and reheat-treated and aged-after-welding) were shown to increase with decrease in temperature to -423°F. The elongations generally remained relatively high. This alloy appears to offer medium-high strength and high toughness similar to that of the high-strength aluminum-magnesium series of alloys plus the advantages of response to postweld thermal treatments.
