摘要： PURPOSE: To obtain a titled superconductive base material having stable superconductive characteristics with respect to a quick change of magnetic field, by working a composite body of a Cu alloy base body contg. Ti, Zr and Hf, an SN base body and an Nb base body to a wire, tape, tube or the like then subjecting the same to a diffusion heat treatment to form an Nb
3 Sn compd. phase.
CONSTITUTION: A composite body of a Cu alloy base body contg. 0.1W5atom% of ≥1 kinds among Ti, Zr, Hf which are IVa group elements, an Sn base body and an Nb base body is manufactured. After such composite body is worked to the above-described shape, the body is subjected to a diffusion heat treatment at 400W900°C to form an Nb
3 Sn compd. around the Nb base body. The amt. of the Sn to be combined to one body with said composite body or the Sn to be coated thereon is adequately 1W50vol% of the entire sectional area. The Nb
3 Sn superconductive wire rod obtd. by the above-mentioned device has large critical current capacity, and contributes to the improvement of performance in various apparatus utilizing the superconductor and to the reduction in a cooling cost due to the reduction in their sizes.
