Alloying metallurgy is confronted with increasing complexity, as requirements of metallic high-tech materials rise with regard to composition, cleanliness and homogenity. In order to comply with strict tolerances, metallurgical vacuum processes are applied, which allow, for instance, melting of metals with high oxygen affinity, removal of dissolved gases or non-metallic inclusions as well as selective distillation of volatile metals. The available equipment at IME for these purposes comprises various vacuum induction furnaces, a pressure-slag-remelting unit and a vacuum arc furnace. Currently research on the following projects is conducted:
– Alternative production methods of Cu-Cr-alloys
– Influence of a rotating electrode on the ESR-process
– Processing of lead-containing copper alloys in consideration of current EU regulations
