Abstract: The invention relates to a process for forming a laminate comprising a core of a compressed metal powder mixed with a foaming agent between two metal layers, comprising the successive steps of providing two metal strips and a stock of powder comprising a metal powder mixed with a foaming agent; applying a layer of the powder between the two metal strips; feeding the metal strips, with the powder between them, to a rolling mill; rolling the two strips with the powder between them to form a laminate of compressed powder between two metal layers. The invention also relates to an associated device and to the product formed using the process.
