Abstract

Incoloy 800H/HT is one of the promising candidates for the fuel cladding materials in supercritical water-cooled rectors. In the present study, with the help of a specific thermomechanical processing, we studied the effects of grain size and grain boundary character distribution on the oxidation behavior of Incoloy 800H/HT in supercritical water (SCW). The processed samples were exposed to supercritical water at 600 ºC and 25 MPa for 100, 300 and 1000 hours. The results showed that grain size and grain boundaries are important factors that affect the oxidation behaviour of Incoloy 800H/HT in supercritical water. We also found that the thermo-mechanical processing improves the adhesion and integrity of oxide scale.
