Abstract
A superconductive composite member comprises a core of oxide ceramic superconducting material that is disposed in a metal envelope comprising a silver alloy which is hardenable by an oxide dispersion. Preferably, the silver alloy is an alloy of Ag--Mg--Ni, Ag--Mn--Ni or Ag--Al alloy which may also include one or more precious metal elements selected from a group consisting of Ru, Rh, Pd, Os, Ir, Pd and Au. The composite member is formed by introducing the superconductive material into the silver alloy envelope, cross section-reducing the assembly of the envelope and core and, subsequently, thermal treatment for the recovery and setting of the oxygen concentration.
