Most of electrochemical properties of thin materials are closely related with the
microstructure of the thin films. In this paper, we review the preferred orientation dependency of
metals in aqueous solutions. For example, aluminum foil etching in highly concentrated hydrochloric
acid solution, etching of invar sheet for shadow masks, and texture related stress corrosion cracking of
metals and alloys are discussed. All the phenomena were interpreted in terms of elastic properties of
thin films and bulk materials.
Keywords: Aluminum, corrosion, etching, invar, stress corrosion cracking, texture, thin film.
