Description

The oxidation behaviour of Zr-based bulk amorphous alloy Zr65Cu17.5 Ni10 Al7.5 has been studied in air environment at various temperatures in the temperature range 591-684 K using a thermogravimetric analyser (TGA). The oxidation kinetics of the alloy in the amorphous phase obeys the parabolic rate law for oxidation in the temperature range 591-664 K. The values of the activation energy and pre-factor as calculated from the Arrhenius temperature dependence of the rate constants have been found to be 1.80 eV and 2.12 x 109 g.cm-2.sec-1/2, respectively.
