This article presents the processes developed by CTIF to make metallic foam-like structures by the foundry route. These processes are based on the “infiltration” technique, similar to conventional foundry techniques, in which a preform, a sort of porous core, is infiltrated with molten metal. By the way, complex shaped cellular parts with skins (intrinsically linked to the cellular structure) can be reproducibly manufactured.
