“…Heavily cold-drawn Cu-Nb composites attract great attention of materials researchers, as they possess an extremely high strength along with good electrical conductivity and thus may be used in high field pulsed magnets [1]. In situ Cu-Nb composites are formed at drawing or rolling of ductile two-phase mixtures of Cu and Nb, the volume of the latter being up to 20 wt.…”

The structure and properties of in situ Cu-Nb composites have been studied by the methods of TEM and SEM, X-ray analysis and mechanical testing. The evolution of Nb filaments structure at drawing and the effect of annealing and doping with Zr on the composites structure and texture have been investigated. Sharp fibre texture with <110>Nb develops in the ribbon-shaped Nb filaments, while the Cu matrix possesses a two-component fibre texture, <111>Cu and <100>Cu, appreciably affected by annealing. Annealing results in softening due to Nb filaments coagulation. In Zr doped composites two types of ZrO2 particles are observed, dispersed and coarse ones. The former result in the dispersion strengthening, while the latter may cause embrittlement.

Wire samples of Cu-Nb and Cu-Ag were wound around a 15 mm diameter mandrel to replicate the circumstances of pulse magnet winding. Longitudinal and transverse sections were prepared for electron microscopy and analysis from both wound and non wound samples. Microstructural investigation of these sections shows that micro-cracking occurs at the tension side of the wire with corresponding deformation at the compression side. Investigation of the sections of non wound samples show that filament size and distribution is not uniform in these conductors.
