Nb based superconductor composites

The technology for the manufacture of composite superconductor material is well established. An excellent paper (1) covering the technology of superconducting composites has been written by H. Hillman for publication in The Proceedings of NATO Advanced Study Institute on Superconducting Materials Science and Technology. In this paper, I will address the relative manufacturing merits of several different composite approaches, including filled billet, powder, in-situ casting, and rolled sheet methods...(AU)
