<p>The reinforcement of articles of cast metal or metal alloy is formed by a mass of whiskers or fibers bound together by a binder such as starch which is such that, on casting, the molten metal penetrates the reinforcement without deforming the reinforcement and dries off the binder by burning or vapourizing the binder. The casting process is preferably a squeeze casting process and the article produced may be a fibre or whisker reinforced piston for an internal combustion engine made of aluminium or aluminium alloy. </p> |
