摘要： A method for casting an aluminum wheel comprises preparing a melt having a predetermined chemistry and including silicon in a range from 8.5 to 10% mass and aluminum; degassing and refining the melt; adding a grain refiner including aluminum-titanium-vanadium-boron (Al—Ti—V—B) and a master alloy to the melt; and casting the aluminum wheel.
