Abstract:
A ceramic dispersoid in metal product, comprising:(a) at least about 50 volume percent of a matrix metal of aluminum; and(b) up to about 50 volume percent of a uniform distribution of finely sized titanium carbide ceramic phase particles formed and dispersed in-situ in said aluminum metal matrix, wherein said finely sized ceramic phase particles have an average particle diameter of less than about 2.5 microns, and wherein said uniform distribution consists of a substantially cluster-free distribution of no more than two particles attached to one another at a magnification of 500X, wherein said ceramic dispersoid in metal product is formed by the process of providing said metal matrix in a liquid state containing liquid titanium and reacting a salt bath containing carbon with said liquid titanium element to form said uniform distribution of finely sized titanium carbide ceramic phase particles formed and dispersed in-situ in said aluminum metal matrix.
