| Summary: | The results from Raman spectra and XRD demonstrated that the surface oxides were mainly composed of iron oxides enriched with chromium and spinel type oxide for high temperature oxidized 2205 duplex stainless steels. The EBSD analysis indicated that the austenitic phase showed more excellent antioxidant ability than the ferritic one. The relative higher IQ value could improve high temperature antioxidant ability of the 2205 duplex stainless steel. The KAM maps showed a relative high value near the grain boundaries and near the interface. In addition, the high temperature oxidation inducing deformation could occur based EBSD analysis. |
