Abstract
A process for producing a cube textured foil is described. The process includes providing a cube textured metal foil M. The process further includes electroplating an epitaxial layer of an alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M. The process further includes electroplating a non-epitaxial layer of an alloy on the epitaxial layer. The process further includes separating the electroplated alloy from the cube textured metal foil M to obtain an electro-formed alloy with one cube textured surface.
Claims29
A process for producing a cube textured foil, comprising:
- providing a cube textured metal foil M;
- and
- electroplating an epitaxial layer of an alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M.
A foil comprising a first layer of Ni(1-X-Y)BXCY having a cube texture overlying a untextured layer of Ni(1-X-Y)BXCY, wherein B and C are selected from the group consisting of W, Mo, and Cr;
- and wherein X is 0.02-0.14 and Y is 0-0.14.
A high temperature superconductor (HTS) tape, comprising:
- a substrate comprising a first layer of Ni(1-X-Y)BXCY having a cube texture overlying an untextured layer of Ni(1-X-Y)BXCY, wherein B and C are selected from the group consisting of W, Mo, and Cr;
- and wherein X is 0.02-0.14 and Y is 0-0.14;
- at least one buffer layer disposed on the first layer of the substrate, the at least one buffer layer having a cube texture which substantially replicates the cube texture of the first layer of the substrate;
- and
- at least one HTS layer disposed on the at least one buffer layer;
- the at least one HTS layer having a cube texture which substantially replicates the cube texture of the at least one buffer layer.
A process for producing a cube textured foil, comprising:
- providing a cube textured metal foil M;
- electroplating an epitaxial layer of an alloy on the foil M, whereby the epitaxial layer substantially replicates the cube texture of the metal foil M;
- wherein the epitaxial alloy layer comprises Ni(1-X-Y)BXCY;
- and
- electroplating at least one non-epitaxial layer of Ni(1-X-Y)BXCY on the epitaxial layer;
- wherein B and C are elements selected from the group consisting of W, Mo, and Cr;
- and wherein X is 0.02-0.14 and Y is 0-0.14, in atomic fractions.
