Abstract

The effect of thiosulphate ions on the pitting corrosion and stress corrosion cracking behaviour of solution-treated INCONEL 600 alloy was investigated. In the absence of chloride ions, pitting corrosion was observed on the specimen surfaces of solution-treated INCONEL 600 alloy, in thiosulphate solution. Intergranular stress corrosion cracking in this material was also found to occur in thiosulphate solution at 95 °C and at applied potentials of -440 and +100 mV (SCE). Crack growth rates as a function of stress intensity (da/dt vs. K) at these two potentials are reported. The possible mechanism for these observations is discussed.
