ABSTRACT:
Provided herein is a method for refining primary silicon present in a hypereutectic aluminum silicon alloy. The method contemplates the controlled application of pressure to refine the primary silicon during the casting of articles. The application of pressure decreases the primary silicon particle size to improve the machinability and wear resistance of the final cast articles.
