Cross-section showing the cube-textured material bonded to an untextured but mechanically strong and nonmagnetic material

Technology Marketing SummaryA novel method of manufacturing single crystal substrates for the entire array of High Temperature Superconductivity (HTS) applications. The process is based on ultrasonic bonding. The result is a mechanically strong, nonmagnetic material.DescriptionAll current HTS applications including HTS wire/cable; electronic, magnetic, and optical sensors that are used in quantum computing applications and medical imaging devices; fault current limiters that prevent power surges from destabilizing local grids; HTS dynamic synchronous condensers that maintain a near-uniform level of voltage in the power grid; electronic filters used in the base stations that route cell phone calls; magnetically levitated trains.Benefits
  • Nonmagnetic substrate
  • Mechanically strong substrate
Applications and Industries

Composite biaxially textured substrates using ultrasonic consolidation
A method of forming a composite sheet includes the steps of: providing a first sheet having a surface and including a metal or alloy, the first sheet having a given strength characteristic; providing a second sheet having a surface and a strength characteristic that is superior to the given strength characteristic of the first sheet; disposing the first sheet and the second sheet in an aligned opposing position with at least a portion of the surface of the first sheet touching the surface of the first sheet to form a contact area; and bonding the first sheet to the second sheet at least in part by applying an oscillating ultrasonic force to at least one of the first sheet and the second sheet to form a composite sheet, the first sheet having a cube texture characterized by a .phi.-scan having a FWHM of no more than 15.degree. in all directions.
