Abstract
An alloy that contains at least two metals and can be used as a substrate for a superconductor is disclosed. The alloy can contain an oxide former. The alloy can have a biaxial or cube texture. The substrate can be used in a multilayer superconductor, which can further include one or more buffer layers disposed between the substrate and the superconductor material. The alloys can be made a by process that involves first rolling the alloy then annealing the alloy. A relatively large volume percentage of the alloy can be formed of grains having a biaxial or cube texture.
Claims18
An alloy, comprising:
- a first metal;
- a second metal different than the first metal;
- and
- at least one oxide former,
- wherein a total amount of oxide former in the alloy comprises at least about 0.5 atomic percent of the alloy, each oxide former is different than the first and second metals, the second metal is nickel, the alloy comprises at least about 25 atomic percent nickel, and the alloy has a biaxially textured surface.
An alloy comprising:
- copper;
- from about 25 atomic percent nickel to about 55 atomic percent nickel;
- and
- at least about 0.5 atomic percent of at least one metal selected from the group consisting of Mg, Al, Ti, Ga, Ge, Zr, Hf, Y, Si, Zn, Sn, B, Pr, Eu, Gd, Tb, Dy, Ho, Lu, Th, Er, Tm, Be, Ce, Nd, Sm, Yb and La,
- wherein the alloy has a biaxially textured surface and at least about 65 volume percent of the alloy comprises grains having a biaxial texture.
The method comprising:
- making an alloy that comprises a first metal, a second metal different than the first metal,
- and at least one oxide former,
- wherein a total amount of oxide former in the alloy comprises at least about 0.5 atomic percent of the alloy, each oxide former is different than the first and second metals, the second metal is nickel, the alloy comprises at least about 25 atomic percent nickel, and the article has a biaxially texturedn surface.
