New Al5 Multifilamentary Superconductor Based on the Niobium--Aluminum--Silicon System

摘要

Based on Powder Metallurgy techniques, a process to fabricate Nb-Nb sub 3 (Al,Si) multifilamentary superconducting wire has been developed. Optimum sintering and infiltration parameters are listed and the methods of mechanical reduction to wire form are described. Preliminary data indicate that diffusion reaction temperatures as low as 850 exp 0 C form the A15 superconducting compound Nb sub 3. (ERA citation 03:048301)
