ABSTRACT:
A stabilized super-conductor of the type containing a super-conductive region consisting of an intermetallic compound containing at least two elements, such as Nb.sub.3 Sn, and a normally-conductive region containing a material which is normally conductive during operational temperatures of the super-conductive region, such as Cu, with a diffusion-inhibiting layer, such as at least partially composed of Ta, positioned between the super-conductive and the normally-conductive regions is produced by providing a structure composed of a region of normally-conductive material and a region of super-conductive material, arranging a plurality of rod-shaped segments, at least some of which are composed of a diffusion-inhibiting material, between the normally conductive and the super-conductive regions and deforming the resultant structure one or more times, with intermediate annealing so as to attain a conductor having a desired reduced cross-section while causing the rod segments to combine with one another to form a diffusion-inhibiting layer.
