Abstract
The invention is a method for adding substantially insoluble material to an at least partially liquid metal. The method comprises providing a combination of a first metal having discrete degenerate dendrites and a plurality of insoluble particles at least partially suspended in the first metal. The combination is mixed with a second metal at a temperature above the solidus temperature of the first metal and the second metal. The second metal is capable of forming a dendritic structure when cooled from a liquid state to a solid state. The mixture is then solidified into a dendritic-containing metallic structure having a plurality of substantially insoluble particles at least partilly suspended in the structure.
