Zusammenfassung:
Fiber or ribbon reinforced in-situ metal matrix composites (MMCs) consisting of Cu and 20 wt.% Nb can be produced by large strain wire drawing. The microstructure of the composites is investigated by means of optical and
electron microscopy. The normal and superconducting properties of the MMC wires in the presence of external magnetic fields are examined and compared to
the electromagnetic properties of pure Cu wires. The findings are discussed on the basis of the microstructural changes during deformation. The current results substantiate that the amount of internal boundaries and the filament spacing have considerable influence on the normal and superconducting properties of Cu-20%Nb.
