Abstract: PURPOSE: A method for fabricating wear-resistant and heat-resistant hypoeutectic aluminum alloys by a field control is provided to improve efficiency by rapidly producing an alloy at a low casting temperature and to reduce a coefficient of thermal expansion by multiplying a content of silicon. CONSTITUTION: A method for fabricating wear-resistant and heat-resistant hypoeutectic aluminum alloys by a field control is as follows. A hypoeutectic aluminum alloy contains AL as a basic component and includes 8.0 to 10.0wt.% of Si, 1.5 to 2.5wt.% of Ni, 3.0 to 4.5wt.% of Cu, Fe maximum 1.0wt.%, and 0.7 to 1.0wt.% of Mg. The hypoeutectic aluminum alloy contains impurities such as Cr and Ti. A field control with respect to Al, Si, Ni, Cu, Fe, Mg, Cr, and Ti is performed through an electromagnetic stirring at a melting temperature of 585°C(S10). Molten metal is cast(S20).

Abstract: A method for bonding dissimilar aluminum using centrifugal casting is provided to produce products of high strength and abrasion-resistance while reducing the failure rate by making the cast structure fine. A method for bonding dissimilar aluminum using centrifugal casting comprises a first step of heating up the inner wall of a mold of a true-centrifugal caster, a second step of injecting molten metal to be used as an outer material into the mold, a third step of agitating while injecting molten metal to be used as an inner material into the mold, and a fourth step of cooling after hardening the molten metal.
