Abstract
An alloy having a cube textured substrate is disclosed. The alloy includes two different metals. The alloy can be used as a substrate for a superconductor. Optionally, one or more buffer layers can be disposed between the substrate and the superconductor material. The alloy can be prepared using a process that includes rolling the alloy and annealing the alloy. The alloy can have a relatively large volume percent that is formed of grains with cube texture.
Claims14
A method, comprising:
- forming a substantially homogeneous alloy comprising nickel and chromium, the alloy having a cube textured surface, wherein at least about 65 volume percent of the alloy comprises grains having a cube texture, and wherein the alloy has an X-ray diffraction pole figure with a full width at half maximum of less than about 20°,
- wherein the method includes rolling the alloy to obtain the cube texture.
