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.
Claims1
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.
