Complex Modifier on Microstructure in Mg2Si/Al-Si Composite
The effects of complex modifier (consisted of mixed rare earth oxides and CaCO3) on microstructure in Mg2Si/A1-Si composite are researched. The results show that the morphology of Mg2Si particle changes from irregular or crosses to polygonal shape, and its size obviously decreases. The modifier presents the better modification than mixed rare earth oxides or CaCO3.
