Title:
金属発泡物および該金属発泡物から成る部品を粉末冶金的に製造する方法
Document Type and Number:
Japanese Patent JP2009503260
Kind Code:
A
Abstract:
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.
