Abstract

The oxidation behavior of two Cu-base bulk metallic glasses (BMGs), having compositions Cu-30Zr-10Ti and Cu-20Zr-10Ti-10Hf (in at.%), was studied over the temperature range of 350-500 °C in dry air. In general, the oxidation kinetics of both BMGs followed the parabolic rate law, with the oxidation rates increasing with increasing temperature. The addition of Hf slightly reduced the oxidation rates at 350-400 °C, while the opposite results observed at higher temperatures. It was found that the oxidation rates of both BMGs were significantly higher than those of polycrystalline pure-Cu. The scales formed on both BMG alloys were strongly composition dependent, consisting of mostly CuO/Cu ₂O and minor amounts of cubic-ZrO ₂ and ZrTiO ₄ for the ternary BMG, and of CuO, cubic-ZrO ₂, and Zr ₅Ti ₇O ₂₄ for the quaternary BMG. The formation of ternary oxides (ZrTiO ₄ and Zr ₅Ti ₇O ₂₄) was inferred to be responsible for the fast oxidation rates of the BMGs. © Springer Science+Business Media, LLC 2007.
