Method of preparing oxide superconducting wire. |
摘要 |
<p>In a method of preparing an oxide superconducting wire comprising the steps of filling up raw material powder for an oxide superconductor in a metal sheath, performing first rolling in this state for working the metal sheath into a tape, performing first heat treatment, then performing second rolling and further performing second heat treatment, diameters of rolls employed for the second rolling are made larger by at least 5 cm than those of rolls employed for the first rolling, in order to improve the critical current density of the as-formed oxide superconducting wire over its longitudinal direction.</p> |
