Stress corrosion cracking relation with dezincification layer-induced stress

From: Metallurgical and Materials Transactions | Date: June 1, 2001| Author: | Copyright information

Brass foil with a protective layer formed on one side was deflected during corrosion in an ammonia solution under various applied potentials, and then corrosion-induced stress generated at brass/dezincification layer under different potentials could be measured. At the same time, susceptibility to stress corrosion cracking (SCC) of brass in the ammonia solution under various applied potentials was measured by using a single-edge notched specimen. At open-circuit potential, both corrosion-induced tensile stress and susceptibility to SCC (Isigma) had a maximum value. Both tensile stress sigmap ...
