The purpose of this project was to develop a conductor design and a manufacturing procedure for a composite multifilamentary Nb/sub 3/Sn conductor suitable for winding a magnet for use in a fusion energy power plant. Effort was concentrated on the design of a conductor with tubular niobium filaments in a copper matrix. Bronze in the bores of the filaments would react with the niobium to form Nb/sub 3/Sn on the inside diameter of the niobium tubular filaments during a heat treatment at final size. Four filament geometries were evaluated. The addition of titanium to the bronze was found to increase the current density. The use of a hydrogen atmosphre did not appear to cause any increase in current density. Primary billets were assembled and extruded with five tubular filament designs and for comparison, five rod type filament designs. Billet designs are described.
