Description

Stoichiometric Zr3Al-based alloy consisting of α-Zr(Al) and Zr3Al phases has been exposed isothermally to dry oxygen at temperatures of 701-828 K. Cubic ZrO2 was formed below 750 K, above that temperature monoclinic ZrO2 appeared beside the cubic phase. The α-Zr(Al) phase was found to be more reactive than Zr3Al. Oxidation obeys a parabolic rate law, with an activation energy of 161.95 kJ. (orig.)
