摘要： An alloy that contains at least two metals and can be used as a substrate (901) for a superconductor (900) is disclosed. The alloy can contain an oxide former. The alloy can have biaxial or cube texture. The substrate can be used in a multilayer superconductor, which can further include one or more buffer layer (902) disposed between the substrate and the superconductor material (903). The alloys can be made by a process that involves first rolling the alloy, and then annealing the alloy. A relatively large volume percentage of the alloy can be formed of grains having a biaxial or cube structure.

摘要： An alloy article having improved oxidation resistance and biaxially textured surfaces formed by thermo-mechanical techniques has up to 60 atomic % nickel, 0.1 to 25 atomic % of an oxide former selected from Mg, Al, Ti, Cr, Ga, Ge, Zr, Hf, Y, Si, Pr, Eu, Gd, Tb, Dy, Ho, Lu, Th, Er, Tm, Be, Ce, Nd, Sm, Yb, La, and mixtures thereof, with the balance copper. The surface smoothness of the article may be improved by thermomechanical techniques without impairing its surface texture. The CTE of the article may be reduced and its mechanical strength increased by incorportation of additional materials into the article without impairing its surface texture. The alloy article is useful as a conductive substrate for superconducting composites where the substrate is coated with a superconducting oxide. Methods of producing the alloy article by melting and sheath and core thechniques are also disclosed.
