| Abstract: | The modificatim effect of strontium-.Sodium,titanium and boron-Containing Composite modifier on Al-Si-Cu alloy has been researched. Comparing with the Strontium-only Containing modifier,the composite modifier is more effective on grain refining of etectic structure,and the effectiveness is more prolongable. |
