This report presents results for the first year of a three-year program. The objective of this program is to understand the stress corrosion cracking (SCC) behavior of high-strength ingot and powder metallurgy aluminum alloys, and in particular to understand the role of hydrogen in such cracking. The approach taken was to study microstructural effects on both hydrogen embrittlement and SCC, and to establish, insofar as possible, microstructural and fractographic correlations with cracking behavior, and detailed understanding of the mechanical behavior of hydrogen-charged material.
