    摘要： A process for manufacturing a superconducting elongated article such as a superconducting wire which is applicable for manufacturing a superconducting coil or the like. The process includes steps comprising filling a metal pipe with material powder of ceramic consisting of compound oxide having superconductivity, performing plastic deformation of the metal pipe filled with the ceramic metal powder to reduce the cross section of the metal pipe, and then subjecting the deformed metal pipe to heat-treatment to sinter the ceramic material powder filled in the metal pipe. The ceramic material powder may contain compound oxide having Perovskite-type crystal structure exhibiting superconductivity.The metal pipe may selected from a group comprising metals of Ag, Au, Pt, Pd, Rh, Ir, Ru, Os, Cu, Al, Fe, Ni, Cr, Ti, Mo, W and Ta and alloys including these metals as the base. The heat-treatment may be carried out at a temperature ranging from 700 to 1,000.degree. C., The plastic deformation of the metal pipe filled with the ceramic metal powder may be performed in such manner that the cross section of the metal pipe is reduced at a dimensional reduction ratio ranging from 16% to 92% by wire-drawing or forging by means of dies, roller dies, or extruder.

    摘要： An evaporation material is used in manufacturing a VTR tape, a vertical magnetic recording thin film or the like. The evaporation material is a wire comprising a cobalt metal a cobalt--nickel alloy containing not more than 30 weight % of nickel, or a cobalt--chromium alloy containing not more than 30 weight % of chromium. This wire has a diameter of at least 1.0 mm and not more than 10 mm, a tensile strength of at least 400 MPa and not more than 1500 MPa, and an elongation and a reduction of area of at least 5%. The evaporation material has a prescribed crystal structure, with a face centered cubic lattice ratio of at least 0.1 and not more than 1. It is possible to obtain a wire having the above properties by heating the metal material to at least Tu.degree. C. and thereafter performing plastic working of reduction in area of at least 10% in a single pass at a temperature of at least Td.degree. C. and not more than (Tu+200).degree. C. Preferably, the cobalt metal or the cobalt--nickel alloy further contains 0.01 to 0.1 weight % of Mn, Cr, Mg, Zr or Ca. Preferably, the cobalt--chromium alloy further contains 0.01 to 0.1 weight % of Mn, Mg, Zr or Ca.
