Compared with the as-spun specimens, the imprinted specimens developed non-uniform oxide layers under identical heat-treatment conditions. Thermal stress-induced short-range order locally increases the interfacial energy with the amorphous oxide, thereby reducing the critical thickness for crystallization and promoting dendritic growth of tetragonal zirconia. These findings demonstrate that nanoimprint-induced structural heterogeneity critically governs the oxidation behavior and provide new guidelines for engineering durable functional oxide layers in Zr-based metallic glass.
