Abstract
A diamond-containing metal-matrix composite material is formed by dispersing pieces of diamond throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture. The mixture may then be remelted and resolidified at a rate sufficiently high that the metal matrix retains an amorphous structure upon cooling. 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 98 percent total of copper plus nickel. The diamond is preferably low-grade or artificial diamond.
