Production method for aluminium alloys

Abstract

A production method for aluminium alloys includes an addition process of adding into a molten aluminium alloy a precipitation nucleus on which an intermetallic compound is capable of precipitating when the molten aluminium alloy is solidifying and a casting process of casting the molten aluminium alloy containing the precipitation nucleus into a metal mold. The molten aluminium alloy contains a high density of nuclei consisting of the precipitation nuclei separated from a liquid phase of the molten aluminium alloy and initially nucleated nuclei from the liquid phase of the molten aluminium alloy.
