発明の名称 (英語) METHOD FOR PRODUCING METAL FOAM PRECURSOR AND METHOD FOR PRODUCING METAL FOAM 新技術説明会
発明の概要(英語) The purpose of this invention is to easily produce a metal foam precursor and a metal foam without using an expensive foaming agent powder. Adding alumina when conducting friction stir processing (FSP) improves the sphericity of the pores in a metal foam and increases the porosity of the metal foam. A die-cast molding (12) that contains gas in the interior is prepared by means of die-casting. Next, a metal foam precursor (16) is produced by dispersing the gas and pore-forming nuclei contained in the interior of the die-cast molding (12) uniformly in the die-cast molding (12) by means of FSP. The metal foam precursor (16) is expanded through a heat treatment that heats the metal foam precursor (16) to near the melting point thereof to produce a metal foam.
