Žárupevné kobaltové slitiny

Abstract

This bachelor thesis deals with cobalt refractory alloys, analysis of structures of two cobalt alloys for the glass industry and determination of their mechanical properties at elevated temperatures. The theoretical part deals with cobalt, its properties, production, and cobalt alloys. In the case of cobalt alloys, increased attention is given to heat-resistant cobalt alloys. In the practical part, the chemical composition of two samples of alloys were determined, then a structural analysis was performed and the mechanical properties at elevated temperatures were determined by means of a tensile test.
