摘要
Cu-Nb microcomposite wire materials containing N=854 niobium filaments were prepared by bundling and drawing technique. The electrical resistivity of the materials is 0.36 μΩ·cm at 77 K. The conductivity values could be greater than 70%IACS at 293 K. The ultimate tensile strength could reach 915 MPa at room temperature when the sectional area of the materials was larger than 5 mm2. And the fracture surface morphology and the Nb filaments arrangement of Cu-Nb wires were observed by SEM.
