Abstract

The oxidation of (Fe₄₁Cr₁₅Mo₁₄C₁₂B₉Co₇Y₂)₉₇Ta₃ bulk metallic glass (Fe8-BMG) was investigated in dry air at 500–625 °C. The results showed that the oxidation kinetics of the alloy obeyed the parabolic rate law at T ≥ 550 °C, while the mass gain at 500 °C was extremely small. The oxidation rates of Fe8-BMG increased progressively as the temperature rose, especially when having its value at 600 °C which was comparable to that of the commercial 304L stainless steel. The scales formed on the amorphous steel consisted of granular Cr₂O₃, and its grain size increased with increasing temperature.
