US Patent:

55672515, Oct 22, 1996

Filed:

Apr 6, 1995

Appl. No.:

8/417749

Inventors:

Atakan Peker - Pasadena CA
William L. Johnson - Pasadena CA
Robert Schafer - Worthington OH
David M. Scruggs - Oceanside CA

Assignee:

Amorphous Alloys Corp. - Laguna Niguel CA

International Classification:

C22C 900

US Classification:

148522

Abstract:

A reinforcement-containing metal-matrix composite material is formed by dispersing pieces of reinforcement material throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture at a sufficiently high rate that the solid metal matrix is amorphous. Dispersing is typically accomplished either by melting the metal and mixing the pieces of reinforcement material into the melt, or by providing a mass of pieces of the reinforcement material 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.

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.
