AbstractCraze cracks and oxidation appeared on the surfaces of the Mn-Cu weathering steel samples after different soaking times at 1260 degrees C in the oxidizing conditions. EPMA result shows that Cu enriches at the interface of matrix/scale, Cu concentration in pearlite is higher than that in ferrite. OM observation shows that decarbonization phenomenon occurred near surface of steel after soaking in high temperature experiments, which resulted in an obvious decrease of pearlite amount, so more Cu segregation in grain boundaries and formed Cu-enriched phase, and caused serious surface crazing at last. However, under the reducing condition, the craze crack phenomenon did not occur after soaking.
