ABSTRACT:
A method for forming elongated articles including metallic oxide superconductor material by hydrostatic extrusion at temperatures less than about 800.degree. C., and even at temperatures less than about 450.degree. C. The method includes providing superconductive core material that is substantially free of carbon or organic additives and that has an equivalent density at least about 55% of full density, and enclosing the densified material in a metal container, to become a cladding, prior to extrusion. In a preferred embodiment, the cladding material is a dispersion hardened metal or metal alloy.
