Method for the powder-metallurgical production of metal foamed material and of parts made of metal foamed material |
摘要 |
A method for a powder-metallurgical production of metal foamed material and of parts made of metal foamed material includes mixing a pulverulent metallic material including at least one of a metal and a metal alloy; pressing, under mechanical pressure, the mixed pulverulent metallic material so as to form a dimensionally stable semi-finished product; placing the semi-finished product into a chamber that is configured to be sealed pressure-tight; sealing the chamber; heating the semi-finished product to a melting or solidus temperature of the pulverulent metallic material; once the melting or solidus temperature has been reached, reducing the pressure in the chamber from an initial pressure to a final pressure so that the semi-finished product foams so as to form a metal foam; and lowering the temperature of the metal foam so as to solidify the metal foam.
