Abstrakt: A gamma prime strengthened nickel-base alloy was given five different heat treatments to form microstructures ranging from solution annealed to overaged. Stress corrosion tests in 50 pct NaOH and undeaerated water solutions at 316°C showed that material that was overaged sufficiently to produce homogeneous plastic deformation possessed greatly increased resistance to stress corrosion cracking. The results suggest that the stress corrosion resistance of other nickel-base alloys could be significantly improved by suitable heat treatments.
