Abstract

Le présent document concerne un procédé de fabrication d’une bobine d’un filament (1), ledit procédé comprenant les étapes : extruder (2) un mélange de liants cristallins ou semi-cristallins et d’au moins 90% en masse ou 60% en volume de poudre métallique ou céramique de sorte à obtenir un filament ;réaliser une trempe (3) dudit filament à une température de trempe déterminée pour abaisser entre 5% et 15% un taux de cristallinité dans lesdits liants ;enrouler ledit filament (4), autour de la bobine, à une température comprise entre 10°C et une température inférieure à la température de trempe.
