CLAD TEXTURED METAL SUBSTRATE FOR FORMING EPITAXIAL THIN FILM AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an oriented substrate for forming an epitaxial thin film thereon, which has a more excellent orientation than that of a conventional one and high strength, and a method for manufacturing the same.

SOLUTION: The clad textured metal substrate for forming the epitaxial thin film thereon comprises a metallic layer and a silver layer which is bonded to at least one face of the metallic layer. The silver layer has a ä100}<001> cube texture in which a deviating angleΔϕof a crystal axes satisfiesΔϕ≤9°. The oriented metal substrate can be manufactured by hot-working the silver sheet containing oxygen concentration of 30 to 200 ppm and heat-treating it for orientation, and bonding the metal sheet with the oriented silver sheet by using a surface activated bonding process.
