A Study on CaC_2 Refining The Eutectic Al-Si Alloy's Grains
Lu Sheng ( Institute of Metal Material )
This paper introduces the effect of CaC2 refining the eutectic Al-Si alloy's grains. A best grain refinement technology is determined by orthogonal experiments. The results show that the mechanical properties of the eutectic Al-Si alloy can be improved obviously through CaC2 grain refinement and modification.
