Abstract
Al80Yb20 multilayered alloy films were amorphized by ion beam mixing at room temperature. A new metastable phase of hexagonal structure was formed when the irradiation dose was greater than that required to amorphize the alloy films. The metastable phase turned amorphous when the film was annealed at 500 °C for 10 min. It was also found that Al-Yb multilayers could be amorphized by solid state reaction. Al1−xYbx multilayered alloy films, with 17<x<30 at. %, became amorphous through interdiffusion at 450 °C for 20 min.Keywords
