ABSTRACT:
This invention provides a composite composition comprising a metallic matrix having a concentration of third phase solid particles homogeneously dispersed throughout the metallic matrix. The metallic matrix can be liquid, solid or partially solid and can have (a) a dendritic structure or (b) up to 65 weight percent of a structure comprising degenerate dendritic or nodular primary discrete solid particles suspended in a secondary phase having a lower melting point than the primary particles which secondary phase can be solid or liquid. The third phase particles can be metallic, non-metallic or a combination metallic-nonmetallic compositions and have a surface composition which is not wet by the metallic matrix when the matrix is a liquid.
