Abstract
La présente invention concerne un procédé de fabrication d'un article métallique. Le procédé consiste à dissoudre un liant fusible dans un solvant, former une boue de solution et de grains métalliques, évaporer le solvant pour obtenir une masse ou agglomérat poudreux de liant et de grains métalliques, comprimer et mettre en forme cette masse pour obtenir un article ayant une forme et chauffer cet article pour éliminer ce liant et fritter les grains de métal. L'invention est par exemple utilisable lors d'un procédé de moulage par injection ou d'extrusion.
