Abstract Superconductive materials are manufactured by providing a laminated material by combining a material of Nb, V or Mo metal, or alloy or intermetallic compound thereof and a material of Sn, Al, Zr, Ti, Pb, Ge, V, Si, Ga, C or Au element or alloy thereof, winding the laminated material tightly into a coil, covering the coiled body with a shielding layer composed of Nb, Ta or Zr metal or alloy thereof or stainless steel, inserting the coil covered with the shielding layer into a sheath composed of Cu, Al, Ag, Au or Cd metal, or alloy or intermetallic compound thereof or stainless steel, subjecting said sheath enclosing said coil and said shielding layer to a treatment for reducing a crosssectional area of said coil and heat-treating thus treated coil. The laminated material may be inserted into the sheath together with a mechanically reinforcing material in order to improve the strength of the resulting superconductive materials.
The method as claimed in claim 1, wherein said laminated material is produced by laminating a sheet or foil of said material (A) and a sheet or foil of said material (B).
Claim 2
Dependent Claim
39 words
The method as claimed in claim 1, wherein said laminated material is produced by rolling a sheet or foil of said material (A) and a sheet or foil of said material (B) to form a composite sheet or foil.
Claim 3
Dependent Claim
48 words
The method as claimed in claim 1, wherein said laminated material is produced by evaporating, sputtering or plating Sn, Al, Si, Ga, Ge, C or Au on a sheet of said material (A) to coat said material (A) sheet with Sn, Al, Si, Ga, Ge, C or Au.
Claim 4
Dependent Claim
25 words
The method as claimed in claim 1, wherein said treatment for reducing the cross-sectional area of said coil is a rolling, extruding or drawing treatment.
Claim 5
Dependent Claim
31 words
A method as claimed in claim 1 further including providing mechanical reinforcing material disposed on the coiled body, said shielding layer covering said coiled body together with said mechanical reinforcing material.
