Abstract

A design has been developed for three-layer composite substrate tapes based on a nickel-tungsten alloy and corrosion-resistant steel. Materials have been picked and experimental samples of three-layer composite tapes obtained. It has been shown that the substitution of corrosion-resistant steel for ferromagnetic nickel–tungsten alloy in 60% of the tape volume decreases the saturation magnetization of the substrate tape by a factor of 2. The mechanical properties of the composite three-layer tape have been investigated. It has been shown that composite tapes are close in terms of the mechanical properties to tapes made from a homogeneous nickel–tungsten alloy. The conditions for the formation of a sharp cubic texture have been determined.
