The invention mainly concerns a method for preparing metal-matrix composites including at least steps of cold-process isostatic compaction of previously mixed powders (5) and of hot-process uniaxial pressing of the compact (12) resulting fromthe previous step. The inventive method enables metal-matrix composites with improved properties to be obtained. The invention I also concerns a device for implementing in particular the isostatic compaction step comprising a latex sheath (1) wherein the mixture of powders (5) is poured, a perforated cylindrical container (2) wherein is arranged the latex sheath (1), and means (7,10, 11) for I sealed insulation of the mixture of powders (2) contained in the sheath (1). |
