Process for fabricating superconducting ceramic materials by HIP treatment |
摘要 |
A process for fabricating worked superconducting ceramic material of a mean grain size not more than 10 um is disclosed, which comprises the steps of: (a) preparing a metal casing containing a starting powder material having a composition for forming an oxide superconductor; (b) calcining the starting powder material contained in the casing at a temperature range of 850 DEG to 950 DEG C.; (c) subjecting said casing to a HIP treatment; (d) subjecting said casing containing hot deformed material to cold deformation processing; and (e) subjecting said casing to stress relief treatment by annealing in the presence of oxygen.
