We examine and characterize metallic materials and develop new alloys, functional materials and processes for industrial practice

Physical Metallurgy belongs to the founding departments of the fem. Central tasks of the department are the production, processing and metallurgical testing and characterization of metallic materials for the jewelry, dental or electrical industry. This includes alloys and composite materials whose structures and microstructures are examined in terms of mechanical, thermal and functional properties. Particular attention is paid to the relationship between production, processing and loading of materials and alloys in practical use.
