Abstract
Stress corrosion cracking of α-brass in the annealed and cold worked states has been investigated under potentiostatic anodic and cathodic polarisation in Mattsson type solutions in which ammonia has been substituted with methyl, ethyl and butyl amines. A general decrease in cracking susceptibility has been observed from methyl to butyl amine, and the cracking pattern changes from intergranular to transgranular.
The potential range of maximum susceptibility also shifts towards more negative values with the substitution of higher amines. These observations have been explained on the basis of active anodic and cathodic sites influenced by adsorption and polarisation processes.
