PURPOSE:To make easy obtaining of a clad plate having a good adhesion between a superconductive alloy and good conductive metal furthermore a desired size by proceeding to a roll process after good conductors (stabilizing metals) such as copper, silver, and alminum are joined by explosive bonding or pressedly connecting, etc., to both sides of the superconductive alloy such as Nb-Ti or Nb-Zr. CONSTITUTION:Metal good conductors 2 and 3 are mechanically and firmly joined by explosive bonding or pressedly connecting, etc., to both sides of a superconductive alloy 1 with a thickness ratio between the alloy 1 such as Nb-Ti or Nb-Zr, etc., and conductors 2 and 3 such as copper, alminum, silver, etc., is made to be 1:1-1:20. A three layer body thus obtained is processed to a required thickness by a mechanical processing such as forging or rolling, then heat treated for 30 min.-100 hours at temperatures of 250 deg.-450 deg.C. This enables afterward processing to be easily made as a three layer clad thick plate (or block) having a sufficient size can be obtained, and the superconductive metal 1 and the stabilizing metals 2 and 3 are firmly joined. |
