Two most known models of metallic-glass structure—the model of random closepacked spheres and the polycluster model—are considered. Peculiarities of the structure defects of glasses possessing these structures are compared. Stability, life time, diffusional length of the point defects of the dense random packing and polyclusters are essentially different. As a result, radiation damages of metallic glasses are very sensitive to the structure properties. Description of the relaxation kinetics of irradiated metallic glasses of both structure types is developed. As shown, analyses of the radiation-damage storing and evolution should be an effective tool of the metallic-glass structure investigation.
Keywords: metallic glasses, structure defects, relaxation kinetics, radiation damages.
