Abstract
The morphology of fracture surfaces has been examined for inorganic salt-induced stress cracking of polyamides. A variety of inorganic salts and solvents were found to have markedly different activity but a common order of topography across the fractured cross-section. Crazes and other features resemble those found in the solvent cracking of glassy polymers. Tensile tests on treated polyamides suggested a conjoint action of salt and solvent.
