Abstract

The mixture consisting of metal powder and a gas splitting foaming agent powder is compressed by compressing to a open pressed part which. A portion or the whole pressed part is used in the semi-finished product and is combined with a covering layer. In the process for producing a foamed semi-finished product, the semi-finished product is produced by compressing a mixture containing metal powder and gas splitting foaming agent.
