Abstract

A highly-productive method for manufacturing a metal foam, capable of easily manufacturing a molded article having a desired shape is provided. A method for manufacturing a metal foam includes dissolving hydrogen in a mixture containing a molten metal and a thickener, and thereby manufacturing a precursor in which an amount of solid-soluted hydrogen in the metal is saturated, charging the precursor into a mold, and solidifying the precursor charged into the mold under a reduced-pressure atmosphere, or solidifying the precursor charged into the mold and then heating the solidified precursor under a reduced-pressure atmosphere.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for manufacturing a metal foam comprising:
 dissolving hydrogen in a mixture containing a molten metal and a thickener, and thereby manufacturing a precursor in which an amount of solid-soluted hydrogen in the metal is saturated;   charging the precursor into a mold; and   solidifying the precursor charged into the mold under a reduced-pressure atmosphere, or solidifying the precursor charged into the mold and then heating the solidified precursor under a reduced-pressure atmosphere.
