Study on Biaxially Textured Ag Substrates and YBCO High Temperature Superconducting Thin Films

The forming regularity and the processing technology of textured Ag tape possessing single component 110 orientation were studied. And a ll0 <100> textured silver tape was obtained by cold rolling and annealing. Superconducting YBCO films were made grown by pulsed laser deposition (PLD) on the 100 <100>, 110 <211> and 012 <100> textured silver substrates. In order to improve the strength of silver tapes, Cu was added in the silver substrates. The processing technology of textured Ag-Cu (1%, 3%, 5%Cu) tape possessing single component orientation was studied.
