Abstract
Nb3Al multifilamentary wire has been fabricated by a newly developed process, in which a composite consisting of a niobium matrix and a large number of Al‐Mg alloy cores is cold drawn into a wire with ultrafine Al‐Mg alloy filaments (about 0.1 μm), and then heat treated to form Nb3Al filaments by the diffusion reaction between the Al‐Mg alloy cores and the Nb matrix. The wire shows excellent high‐field superconducting properties comparable to those of the practical Nb3Sn multifilamentary wire.Keywords
