Mechanically reinforced Ag-clad Hastelloy tapes were fabricated as the inexpensive substrates for coated conductors without any buffer layer. The clad substrate has good adhesion between Ag and Hastelloy layers. Superconducting YBa2Cu3O7 (YBCO) films were directly deposited on Ag-clad Hastelloy substrates by chemical vapor deposition in high magnetic fields. YBCO films were highly oriented along the c-axis perpendicular to the substrate with a zero resistance transition temperature of 86.2 K and a transport Jc value of 104 A/cm2 at 77 K and zero magnetic field. These results indicate that the present work appears to be a promising way for the development of YBCO films for large-scale applications.
