Abstract

Stress-corrosion behavior of AM 350 steel has been evaluated in natural atmosphere in dose proximity to the oceans. A number of stress corrosion-cracked specimens have been examined by means of electron microfractog-raphy. The salient microstructural features of crack initiation and propagation are described and interpreted.
