Regularities of Changing Amorphous Metallic Alloys Properties under Exposure to External Influences

Abstract:

In this paper we have studied changes in the structure and properties of amorphous metallic alloys in annealing. We have identified the regularity of plasticity decreasing. We have determined that processes decreasing plasticity are thermally activated. The ratio of the alloy components affects the shape of the plasticity-temperature curves. Based on experimental results we have proposed an energy model of the plasticity formation in alloys in annealing, We have determined the relation between a crystallization temperature and the concentration of cobalt in ribbon metallic glasses. We have constructed diagrams of the time-temperature stability which allow establishing acceptable exploitation modes of amorphous metallic alloys and products made from them.
