Continuous High Temperature Gradient Solidification Of In Situ Cu-Nb Alloys For Large-Scale Development

  • Chapter
Advances in Cryogenic Engineering Materials

Part of the book series: Advances in Cryogenic Engineering ((ACRE,volume 28))

Abstract

The in situ technique for preparing multiply connected Nb3Sn (V3Ga) superconducting wires consists of melting and casting a Cu-Nb (V) alloy, mechanically deforming the casting into wires, and finally reacting the Nb (V) filaments into Nb3Sn (V3Ga) by diffusing Sn (Ga). For its relative simplicity, but also for the improved mechanical properties of the resulting composites, the in situ process is a promising alternative to the bronze process. Several groups are evaluating various scale-up approaches1–6 (see also other papers in this volume). We had developed an arrangement for high temperature gradient solidification of small diameter rods.4–5 The choice of a relatively small diameter had the advantages of:

  • low power and inexpensive equipment

  • good dispersion of the Nb along the rod

  • control of the form and the size of the Nb dendrites.
