Abstract
The invention relates to a metal strip made from a layer composite for epitaxial coating and a method for production thereof. The aim of the invention is to produce such a high-strength metal strip and a corresponding production method. Said metal strip is a layer composite made from at least one biaxially-textured base layer of the metals Ni, Cu, Ag or alloys thereof and at least one further metallic layer, whereby the individual further metallic layers are made from one or several intermetallic phases or from a single metal in which one or several intermetallic phases are contained. The production method is characterized in that the formation of intermetallic phases at the end of the production process is carried out by means of interdiffusion of elements provided in the layers. Such strips can be advantageously used, for example, as support strips for the deposition of biaxial textured layers made from YBa.sub.2Cu.sub.3O.sub.x high temperature superconducting material. Said high temperature superconductors are particularly suitable for application in energy technology.
