Abstract:
1. A process of manufacturing a reinforced aluminum alloy, comprising a casting step and a dispersing step, wherein said casting step comprises the steps of: (a) add 3˜3.5% by weight of Al—Si alloy, with 95˜97% by weight of aluminum (Al); (b) melting said Al—Si alloy with said aluminum at a temperature with a range between 700° C. and 800° C.; (c) adding 1.9˜3.3% by weight of Al-Rare Earth Elements and 0.03˜0.10% of Boron (B) with said melted Al—Si alloy and aluminum; (d) adding 0.63˜0.68% by weight of Magnesium (Mg), (e) adding 1.5˜2% by weight of refiner under a temperature between 720 and 740° C. with a refining time between 15 and 20 minutes to proceed a refining process; and (f) placing said materials at a temperature between 680° C. and 710° C. for 13 to 15 minutes; wherein said dispersing step comprises the step of: (g) keeping a temperature of said materials from said casting step at a temperature between 560 and 580° C. for 3.5 to 4.5 Hr; (h) cooling down said materials at a cooling rate of 180˜220° C./Hr to form said reinforced aluminum alloy.
