Abstract

L'invention concerne un procédé pour produire un composant (14) comprenant au moins une couche expansée, constituée d'une ou de plusieurs sortes d'agent d'expansion et d'une ou de plusieurs sortes de poudre métallique, et au moins une couche de métal massif (2 ; 3). Pour former la couche expansée, une poudre comprenant plusieurs constituants est mélangée, puis le mélange (1) ainsi formé est soumis, avec la ou les couches de métal (2 ; 3), à au moins une opération de pression et il est ensuite expansé. Le procédé selon l'invention se caractérise en ce que le produit semi-fini (4) obtenu après l'expansion est introduit dans un outil de formage (9) en deux parties dans lequel il est soumis à une opération de formage.
