METHOD FOR PRODUCING ALUMINIUM ALLOY

摘要

The present invention relates to a method for producing hypereutectic aluminum alloy comprising 14-20 wt% of Si, 2-7 wt% of Ti, and 1-3 wt% of B. The method can minimize generation of TiAlSi phase by charging and dissolving a plurality of master alloys at more than or equal to 900°C, producing molten metal, and rapidly cooling the same at a speed of more than or equal to 10°C/s.
