    Abstract:

    The high strength and high conductivity Cu-18vol.%Nb microcomposites (8733filaments) were fabricated by bundling and drawing process (ADB) for high pulsed magnets field. The influence of heat treatment on the microstructure、mechanical properties、 and magnetic properties of Cu-18vol.%Nb microcomposites were systematically investigated. The sample were characterized by XRD、 SEM、 and TEM. Results show that the intensity of <110>Nb texture decreased at first and then increased with the increases of annealing temperature. At the same time, the significant spheroidization and coarsening phenomenon of the Nb filaments were observed. The influence of the microstructural changes on the mechanical properties and the magnetic properties of the Cu-Nb microcomposites are discussed.
