Abstract

Recently one of the most significant research-field in the development of amorphous alloys is the research of the Cu-based amorphous alloys. The Zr-based alloys developed earlier can be replaced by the newly developed Cu-based alloys as the high price of the Zr-based alloys limits their utilization in spite of their favourable properties. Production of Cu-based alloys having the same or more favourite properties than Zr-based alloys is cheaper and this fact can promote their increasing utilization. Cu-Zr-Ti and Cu-Hf-Ti alloy systems - they are Cu-based alloys - have excellent mechanical properties. In this paper investigations of crystallization of amorphous Cu44,25Zr 36Ag14,75Ti5 powder produced by ball milling (these processes have not been investigated yet according to the reference data) are described. In the course of investigation of the crystallization process, samples were heated to a temperature of investigation by means of a DSC equipment and the developed state was frozen by chilling. The investigation of the developed structure and to identify the phases formed during heat treatment, X-ray diffraction method was used.
