Abstract
An aging process for solution-heat-treated, precipitation hardening metal alloy includes first underaging the alloy, such that a yield strength below peak yield strength is obtained, followed by higher aging for improving the corrosion resistance of the alloy, followed by lower temperature aging to strength increased over that achieved initially.
