摘要：

Highly biaxially textured Ni tapes have been strengthened by introducing Al2O3 particles with internal oxidation. The tape strength could be increased by a factor Of live compared to pure Ni tapes, There from,in engineering current density increase by a factor of 4 can be derived by reducing the substrate thickness, Al-oxide formation at the surface of the tapes is prevented by the design of a composite tape consisting of an At free surface region and an At containing core with about the same strength. In this composite Al2O3 only evolves in the tape core, (C) 2002 Elsevier Science B.V. All rights reserved.
