Abstract
Laboratory procedures were established to produce advanced aluminum 2XXX+ Zr alloy powder metallurgy sheet in the T8X temper. The sheet was tested for tensile and Kahn Tear properties in the longitudinal and long transverse directions. The results from the laboratory-produced sheet were compared to the results of a pilot-scale NASA contractual study which used the same alloy powders, leading to the conclusion that laboratory-scale sheet properties are good to excellent predictors of the pilot-scale tensile properties and tear notch toughness values. Tear resistance toughness at pilot scale was not satisfactorily predicted by the laboratory results.
