Abstract
A metal composition characterized by greater than about 65 weight percent degenerate denritic or nodular primary discrete solid particles suspended in a secondary phase having a lower melting point than the primary particles and which secondary phase can be solid or liquid. The method involves raising the temperature of a metal alloy to a value at which the alloy is largely or completely in the molten state. The melt is then subjected to vigorous agitation in an apparatus having an inner surface contacting the liquid-primary solid composition that is not wet by the composition and the heat is extracted to increase the portion of the mixture is in solid degenerate dendrite or nodular form greater than about sixty-five percent while continuing the agitation.
