Oxidation behaviour of solution-annealed and thermally-treated Alloy 690 in low pressure H2-Steam
Source abstract
Abstract
Oxidation experiments were performed on Alloy 690 in a low pressure H2-steam environment at 480 °C to investigate the effects of the microstructure and thermal treatment on the “precursors events” associated with Primary Water Stress Corrosion Cracking. Advanced analytical electron microscopy characterisation revealed that the Alloy 690 did not exhibit preferential intergranular oxidation but rather only diffusion-induced grain boundary migration promoted by the formation of an external Cr2O3 oxide layer for both material conditions (solution-annealed vs. thermally-treated). These data demonstrate that for Alloy 690 the diffusion-induced grain boundary migration is a necessary but not sufficient condition for preferential intergranular oxidation.
