Al-Si Method of fabrication for hyper-eutectic Al-Si casting alloy

摘要

The present invention relates to a method for producing an over-process Al-Si based cast alloy capable of refining superfine silicon, comprising the steps of: providing an aluminum alloy melt containing aluminum (Al) and silicon (Si); Applying vibration energy to the aluminum alloy me And coagulating the aluminum alloy melt to which the vibration energy has been applied. The present invention also provides a method for producing an over-process Al-Si alloy casting alloy.
