Abstract
A biaxially textured article includes a rolled and annealed, biaxially textured substrate of a metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure; and an epitaxial superconductor or other device epitaxially deposited thereon.

A method of preparing a biaxially textured alloy article comprising the steps of:
- a. rolling and annealing a base metal preform to form a biaxially textured substrate having a surface, said base metal preform having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure, said biaxially textured substrate being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM;
- b. depositing onto said surface of said biaxially textured substrate an alloying agent to form a laminate;
- and,
- c. heating the laminate to a sufficient temperature and for a sufficient time to cause interdiffusion of said base metal and said alloying agent, while maintaining the biaxial texture of said biaxially textured substrate, while transferring the biaxial texture to said alloying agent and while preventing homogeneous melting, to form a biaxially textured alloy article.
