Abstract: A new melting technique-Thermal Rate Treatment (TRT) has been studied in connection with Al Si based alloys. TRT technique obviously improves the impact toughness of the alloys, refines the primary Si phase and increases the amount of the α phase. TRT process greatly affects the result of modification process. The compound treatment of TRT+modification could increase the modification effects of Na or P element. According to the state and its change of Al Si alloy melt, the test results were discussed.
