Thermal stability and oxidation behavior of Cr2AlB2powders were investigated at 600−1200 °C. Cr2AlB2is stable up to 900 °C in argon, partially decomposes into Cr4AlB4and Al at 950−1070 °C, and partially decomposes into CrB and Al at 1090−1200 °C. Oxidation in air initiates at 680 °C and up to 1200 °C exhibits an initial rapid linear oxidation followed by a slow parabolic oxidation behavior. A protective Cr2O3(below 750 °C) or Al2O3(above 800 °C) scale is formed, which makes Cr2AlB2exhibit good oxidation resistance. Based on the calculated free energies associated with the oxidation reactions, a good correlation with the experimental results was found.
