A METHOD OF PRODUCING SUPERCONDUCTING TAPES WITH A HIGH CURRENT DENSITY

摘要

A method of producing superconductors with a relatively high critical current density by a mechanical deformation provided by means of a tool mechanism comprising movable clamping jaws, which are formed in such a way that the final product is of the same thickness everywhere. According to the invention the mechanical deformation is preformed continuously or stepwise continuously by the clamping jaws and the hinged brackets and eccentric arms connected thereto being formed such that during the deformation the same relative coordinate applies in the longitudinal direction, whereby the deformation in the longitudinal direction is neglectable. The resulting deformation method highly resembles a uniaxial pressing.
