摘要:
A method of pressure casting a turbocharger component for an internal combustion engine may include heating an aluminum-scandium alloy to form a molten casting material including up to about 5 wt % scandium that is fully dissolved in the molten casting material, and introducing the molten casting material into a cavity of a mold from a bottom of the mold toward a top of the mold while applying a pressure to the molten casting material with a movable portion of a ram positioned in contact with the bottom of the mold. The method may also include solidifying the molten casting material by cooling the casting material as it comes into contact with a cooling member positioned on the top of the mold, wherein a coolant is pumped through coolant passages formed in the cooling member in order to cool the casting material at a cooling rate such that the solidifying preserves at least 70% of an original amount of the scandium in the aluminum-scandium alloy in solid solution in the casting material. The method may still further include removing the solidified casting material from the mold, and forming scandium precipitates within the casting material by aging the casting material at an aging temperature.

An Al alloy cast product includes 3.2% to 7.2% by weight of Mg and 0.28% to 0.6% by weight of Sc, and has an Fe content and an Si content, each of 0.1% by weight or less. The cast product contains, in the metal texture, 3% by volume or less of Al3Sc particle having a particle diameter of 100 nm or less. In production thereof, an Al alloy melt containing 3.2% to 7.2% by weight of Mg and 0.28% to 0.6% by weight of Sc and having an Fe content and an Si content, each of 0.1% by weight or less, is prepared. Next, a casting formed from the melt is subjected to an aging treatment without a solution heat treatment (or a quenching treatment). Then, 3% by volume or less of Al3Sc particle having a particle diameter of 100 nm or less is precipitated in the metal texture.
