IMPROVED PROCESS FOR CASTING OF ALUMINIUM OR ALUMINIUM ALLOYS TO OBTAIN FINE GRAIN REFINING THEREOF

摘要

An improved process for casting of aluminium or aluminium alloys to obtain fine grain refining thereof comprising innoculating the molten metal with a wire of aluminium, titanium and boron, prior to solidification of the cast, at a temperature of 700 to 900degrees C the composition of metals used for the wire consists of 0.1 to 10% of titanium 0.5 to 4% by weight of boron the balance being aluminium.
