Rejuvenating treatments demonstrated. Experiments with three alloys show some combinations of heat treatment, hot isostatic pressing, and/or surface treatment extends cycle lives of fatigue-damaged or fatigue-precracked specimens. For each alloy, tests were first done to determine "baseline" high-cycle-fatigue lives and high-cycle-fatigue failure modes over range of test conditions. Controlled fatigue damage introduced into specimens. Damaged specimens subjected to candidate rejuvenating treatments, then tested to failure. Effectiveness of each treatment judged by comparing fatigue data of damaged and treated specimens to "baseline" fatigue and data taken at same test conditions.
