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.
Claims16
A biaxially textured alloy article comprising a rolled and annealed biaxially textured metal substrate, said metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure, said biaxially textured metal substrate comprising one or more metals selected from a group consisting of Cu, Ni, Al, and Fe and being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM;
- and a biaxially textured layer of an alloy on a surface thereof, said biaxially textured layer being of a different composition than said substrate.
A biaxially textured laminate article comprising a rolled and annealed biaxially textured metal substrate, said metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure, having an epitaxial layer of another material on a surface thereof, said biaxially textured metal substrate comprising one or more metals selected from a group consisting of Cu, Ni, Al, and Fe and being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM.
A superconductor article comprising a rolled and annealed, biaxially textured metal substrate, having an epitaxial barrier layer thereon, and an epitaxial superconductor layer on said barrier layer, said biaxially textured metal substrate being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM.
A polycrystalline biaxially textured article comprising a metal substrate, said metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure, said biaxially textured metal substrate comprising one or more metals selected from a group consisting of Cu, Ni, Al, and Fe and being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM;
- and a biaxially textured layer of an alloy on a surface thereof, said biaxially textured layer being of a different composition than said substrate.
A polycrystalline biaxially textured laminate article comprising a biaxially textured metal substrate, said metal having a face-centered cubic, body-centered cubic, or hexagonal close-packed crystalline structure, having an epitaxial layer of another material on a surface thereof, said biaxially textured metal substrate comprising one or more metals selected from a group consisting of Cu, Ni, Al, and Fe and being characterized by an x-ray diffraction phi scan peak of no more than 20.degree. FWHM.
