発明の名称 (英語) METAL FOAM PRODUCTION METHOD AND METAL FOAM PRODUCTION DEVICE NEW
発明の概要(英語) The present invention provides a metal foam production method that enables a foaming process to be performed at low cost and enables controlling of the shape of metal foam. According to the present invention, a mold that transmits light and a precursor prepared by mixing a metal with a foaming agent are used, and a metal foam is produced by irradiating the precursor with light that has transmitted through the mold, heating and foaming the precursor so as to prepare a metal foam, and controlling the shape of the metal foam by the mold.
従来技術、競合技術の概要(英語) BACKGROUND ART
The metal foam, by including a large number of pores, and light in weight, impact energy absorption characteristics of the noise and the ability to, automobile, railroad, aerospace, building or the like, in various fields as an ultra-light weight multi-functional material has attracted attention (for example, Patent Document 1-to Patent Document 3 the reference.)
As a method of manufacturing the foam metal, in the prior art, for example, the foaming agent is mixed with raw material metal after formation of a precursor, the precursor by heating in an electric furnace or the like, decomposition of the blowing agent that is foamed by gas generated by the porosity that has been formed. In addition, the foam precursor in the step, the mold for molding of the foam metal has been used (for example, Non-Patent Document 1 (e) with reference to Fig. 1).
