Abstract:

Overaged 7075 aluminum alloy, possessing inherently high resistance to stress-corrosion cracking, was forged or rolled to regain the strength lost by overaging. The reductions that would be required were overestimated, so that excessively thick sections were used as starting material. Neither forging nor rolling of overaged 7075 caused any failures within a 30-day test period.
