Abstract
Abstract 316 L(N) austenitic steel was corroded at 550 °C in liquid sodium containing 200 μg g−1 dissolved oxygen from 242 h to 7704 h. NaCrO2 is formed for all immersion times, O and Na from liquid metal and Cr from steel. The oxidation front is located at the chromite / steel interface and in the steel grain boundaries. M6C carbides (M = Mo and Fe) are also formed, C from liquid sodium. NaCrO2 is dissolved until the saturation of liquid sodium in Cr is reached. The Cr solubility is higher than that of pure Cr due to the presence of dissolved oxygen.
