OSTI ID:5522517
Supercon, Inc. has been engaged in a development program for the manufacture of composite Nb/sub 3/Sn conductors containing filaments of Nb-Nb/sub 3/Sn - Bronze in a high conductivity copper matrix. This report covers a portion of the development program that was focused on an improved technique for fabricating the basic niobium clad bronze material for the filaments. Heretofore, the filaments were made from niobium tubes containing bronze rods. The new technique involves the fabrication of a preliminary extrusion billet containing a core of copper-tin bronze with niobium sheet wrapped around a bronze core. Sufficient wraps are used to give the desired bronze-niobium ratio. The niobium wrapped bronze is sealed in a copper billet and extruded. The resultant rod is reduced further and assembled into multifilamentary billets for processing into composite multifilamentary conductor.
