摘要 |
An oxide superconducting material is coated with silver or an alloy thereof and shaped into a linear body, and the linear body is subjected to diameter reduction by means of groove roll rolling, a swaging machine and the like, and then differential speed rolling and heat treatment are repeatedly performed, whereby the linear body is shaped into a tape-shaped wire material. The microstructure control in the longitudinal direction is performed uniformly and efficiently, and a superconducting wire having a high c-axis orientation ratio and a large critical current density Jc at a service temperature is obtained. |
