Procedures have been developed for casting 10 cm diameter Cu-Nb ingots and for fabricating these castings into Nb/sub 3/Sn-Cu in-situ wire. Operating conditions which produce consumable arc cast ingots homogeneous to 1.5 wt % Nb are presented along with analyses of macrosegregation, carbon pickup and Nb dendrite size. Carbon impurity level is found to be an important parameter which controls the critical current.
