Japanese Patent JP3352584

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a method of manufacture of metallic foamed body, capable of inexpensively manufacturing a product of desired shape at arbitrary foaming ratio and also capable of facilitating foaming, with certainty, by the use of equipment of simplified structure under atmospheric pressure. SOLUTION: One or more kinds among metals, alloys, and metal matrix composites, each having >=420 deg.C melting point, are heated and formed into molten metal of <630 deg.C having <=35% solid phase ratio by volume ratio. Titanium hydride in the amount of 0.1-5% by weight ratio is added to the molten metal and uniformly dispersed in the molten metal by agitation, and this molten metal, containing titanium hydride, in a proper quantity is poured into a mold or a metal product. Then, the molten metal in the mold or the metal product is reheated to >=630 deg.C to undergo foaming treatment, followed by solidification by cooling. By this method, the metallic foamed body of prescribed shape can be obtained.
