Abstract

Microfilamentary composites of continuous Nb fibers in Cu matrices prepared by the stack-and-draw method were tested for normal-state electrical conductivity, residual stress state, and tensile properties. Composite wires having nominal filament diameters of about 0.1 μm were characterized by elevated matrix annealing temperatures, large Nb residual strains, and high tensile strengths. In the fine-filament regime, finer wire sizes result in larger matrix resistivities, higher residual fiber strains, and higher tensile strengths with little effect on matrix annealing temperatures.
