摘要：

Multifilamehtary Cu-Nb composites were produced by cold P/M processing. Elementary powders of ^ 40 pjn diameter were first cold extruded and subsequently drawn to wires or ribbons. Cu-M^Sn composites were produced by electrochemical Sn plating of the Cu-Nb composite, followed by a reaction annealing at temperatures between 650 and 850° C, After cross-sectional reduction by a factor R = 500, a sample of the composition Cu-30%Nb(20at %Sn) had a Jc value of 104 A/cm^ at 12 T, which is comparable to the values obtained by other techniques. This cold P/M technique is adaptable to a wide range of superconducting systems and appears to be promising for industrial applications. © 1979 IEEE
