Abstract

L'invention concerne un procédé de préparation de produits, qui est utilisé pour résoudre le problème technique existant selon lequel un traitement est extrêmement difficile lorsque des métaux durs ou des alliages durs sont utilisés pour produire des produits à dureté élevée. Le procédé consiste à : placer une tige de métal dur ou une tige d'alliage dur et une tige d'alliage amorphe dans une cavité prédéfinie pour un mélange ; chauffer le matériau mélangé jusqu'à la plage de température d'une zone de phase liquide surfondue de la tige d'alliage amorphe ; amener la tige d'alliage amorphe à s'écouler dans un état semi-solide au moyen de l'application d'une pression, et entraîner la tige de métal dur ou la tige d'alliage dur mélangée avec la tige d'alliage amorphe afin qu'elles se déforment conjointement selon la forme de la cavité prédéfinie ; refroidir le matériau mélangé pour obtenir un matériau composite ; placer le matériau composite dans un moule de produit ; injecter un matériau métallique liquide dans le moule, de telle sorte que le matériau métallique liquide soit mélangé avec le matériau composite ; appliquer une pression prédéfinie sur le moule et maintenir la pression pendant une durée prédéfinie, et ouvrir ensuite le moule pour retirer le produit.
