Abstract
The high strength and high conductivity Cu-18 vol%Nb composites (8733 filaments) used in high pulsed magnets field were fabricated by bundling and drawing process (ADB). The influence of heat treatment on the microstructure, mechanical properties and magnetic properties of Cu-18 vol%Nb composites was investigated. The samples were characterized by XRD, SEM, and TEM. Results show that the intensity of <110>Nb texture decreases first and then increases with the increases of annealing temperature. At the same time, significant spheroidization and coarsening phenomenon of the Nb filaments are observed. The influence of the microstructural change on the mechanical properties and the magnetic properties of the Cu-Nb composites was also discussed.
