Abstract
Abstract High performance metallic alloys which possess desirable characteristics such as high electrical conductivity, high strength, lightness, high thermal stability, etc. may be prepared by admixing three metals or metalloids by mechanical means. The process will result in the formation of a matrix material consisting of one metal and an intermetallic compound comprising the other two metals or metalloids to provide a finished alloy with the desirable characteristics hereinbefore set forth. The intermetallic compound will be present in a uniform dispersion in the matrix material in the form of particles which possess a size in the range of from about 0.001 to about 0.5 microns.

Claim 1
Independent Claim
172 words
A method for the production of a high performance metallic alloy which comprises mechanically admixing two binary alloys in the solid state under conditions which result in the melding and consolidation of such alloys, the first binary alloy comprising a subsequent matrix material and a metal component of a subsequent intermetallic compound with a second binary alloy comprising the subsequent matrix material and a dissimilar metal, or mechanically admixing one binary alloy comprising the subsequent matrix material and a metal component of a subsequent intermetallic compound with a singular dissimilar metal comprising the second component of said subsequent intermetallic compound, said mechanical admixing step occurring under conditions which result in the melding and consolidation of such alloys to yield said high performance metallic alloy comprised of said intermetallic compound and said matrix material, said intermetallic compound being present in said matrix material in the form of a dispersion of particles which possess a size in the range of from about 0.001 to about 0.5 microns, and recovering said high performance metallic alloy.
