Abstract
Inserts of powder compacts or metal matrix composite inserts in the form of rods, bars, plates, wires, wire mesh, ribbons, chaplets, mold coatings or machining chips are placed in the sprue, sprue basin, runner, or a mold in gate of a static sand mold. The molten metal stream partly or completely melts the inserts releasing the reinforcements which get mixed with the molten alloy streams to form the shaped casting of the composite.
