Title
(EN) AMORPHOUS METAL/REINFORCEMENT COMPOSITE MATERIAL
(FR) MATERIAU COMPOSITE METAL AMORPHE/MATERIAU DE RENFORCEMENT
Abstract
(EN)
A reinforcement-containing metal-matrix composite material (20) is formed by dispersing pieces of reinforcement material (22) throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture at a sufficiently high rate that the solid metal matrix (24) is amorphous. Dispersing is typically accomplished either by melting the metal and mixing the pieces of reinforcement material (22) into the melt, or by providing a mass of pieces of the reinforcement material (22) and infiltration of the molten amorphous metal into the mass. The metal preferably has a composition of about that of a eutectic composition, and most preferably has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel.
(FR)
On forme un matériau composite (20) constitué d'une matrice métallique contenant un matériau de renforcements, en dispersant des particules d'un matériau de renforcement (22) dans une masse en fusion d'un métal capable de se solidifier sous une forme amorphe et en solidifiant le mélange à une vitesse suffisamment élevée pour que la matrice métallique (24) soit amorphe. Habituellement, la dispersion s'accomplit soit en fondant le métal et en mélangeant les particules de matériau de renforcement (22) dans la masse en fusion, soit en utilisant une masse de particules de matériau de renforcement (22) et en infiltrant le métal fondu amorphe dans la masse. Le métal présente de préférence une composition qui est approximativement celle d'un eutectique et, de préférence, le métal contient, en pourcentage atomique, d'environ 45 % à environ 67 % de zirconium plus titane, d'environ 10 % à environ 35 % de béryllium et d'environ 10 % à environ 38 % de cuivre plus nickel.
