Title:
【発明の名称】発泡可能な金属体の製造方法
Document Type and Number:
Japanese Patent JP2898437
Kind Code:
B2
Abstract:
A process for making foamed metal bodies is described, in which a mixture (17) of a metal powder (15) and a gas-evolving blowing agent powder (16) is thermocompacted to form a semi-finished product (19), at a temperature at which the bond of the metal powder particles predominantly takes place by diffusion and at a pressure which is high enough to prevent the decomposition of the blowing agent, in such a way that the metal particles are in a solid bond with one another and represent a gas-tight seal for the gas particles of the blowing agent. The foamable metal body may also be produced by rolling. Furthermore, use of the foamable metal body (19) thus produced for making a porous metal body (21) is proposed.
