Zusammenfassung:An assessment of new materials, heat treatments, and other manufacturing processes for refurbishment and replacement of older-generation, aging components is necessary for a viable life-- extension program. A quantitative database of stress corrosion cracking properties of old-generation materials compared to new-generation materials is needed as a guideline/justification for part replacement.
