EMBRITTLEMENT OF SILVER CHLORIDE BY COPPER CHLOROCOMPLEXES.

Abstract

Previous studies have revealed that when polycrystalline AgCl is deformed in aqueous solutions containing silver complex-ions of charge greater than (2-) or (1+), the fracture mode changes from ductile and transcrystalline, as in air, to brittle and intercrystalline. In the present paper it is demonstrated that complexes not containing silver, viz. copper chlorocomplexes, also can induce brittle behavior in polycrystalline AgCl. The phenomenon of complex-ion embrittlement may be more general than hitherto indicated. Observations on the variation in time to failure of statically loaded specimens with applied stress and with variation of (1) concentration and type of copper chlorocomplexes present in the testing environment (2) composition and temperature of the base environment (HCl or H2O) are discussed.
