    Abstract

    The proper RE addition to cast Al melt can obviously de crease amounts of gas/pin hole in solidified alloy. It is founded that stable RE -hydride was formed resulting in the decrease of free H content. The RE effects on impurity removal decrease heterogeneous nucleation site of bubble to f urther enhance the gas removal and purification effect.
