Method for producing magnetostrictive material, magnetostrictive material, and method for producing energy conversion member

Abstract

A method for producing a magnetostrictive material producible without using a mold, a magnetostrictive material, and a method for producing an energy conversion member; the first method includes melting raw material powder for the magnetostrictive material by a laser or electron beam using a metal 3D additive manufacturing machine to perform additive manufacturing. The raw material powder is composed of an Fe—Co alloy. A method for producing an energy conversion member includes laminating and joining one of a magnetostrictive layer formed by melting raw material powder for a magnetostrictive material by a directed energy deposition method to perform additive manufacturing and a soft magnetic material layer formed by melting raw material powder for a soft magnetic material by the directed energy deposition method to perform additive manufacturing on another.
