Abstract

L'invention concerne un procédé pour préparer un matériau composite d'alliage amorphe contenant des particules ZrC dispersées dans ledit matériau. Ce procédé consiste à ajouter à un alliage mère des particules de carbone et un métal pur Zr ou un alliage Zr, les dissoudre à une température supérieure au point de fusion du métal pur Zr ou de l'alliage Zr + 100 °K, faire réagir Zr avec C pour former des particules ZrC et produire l'alliage mère mentionné ci-dessus capable de former du verre présentant des particules ZrC dispersées uniformément. Des matériaux composites d'alliage amorphe contenant diverses quantités de particules ZrC dispersées dans lesdits matériaux et présentant des formes souhaitées peuvent être préparés. Ce procédé peut être utilisé pour préparer, pour un faible coût, un matériau composite d'alliage amorphe contenant des particules ZrC dispersées dans ledit matériau, lequel matériau présente une excellente résistance mécanique.
