Modification of eutectic silicon and β-Al5FeSi phases in as-cast ADC12 alloys by using samarium addition饶远生1,闫洪1,胡志1,21. Institute of Advanced Forming,Nanchang University2. Jiangxi Key Laboratory for Advanced Copper and Tungsten Materials,Jiangxi Academy of Sciences摘 要:The effects of Sm additions(0,0.5 wt.%,1.0 wt.% and 1.5 wt.%) on the eutectic Si......
. The results show that phosphorus can change the morphology and size of the primary silicon and control the length of needle-like eutectic silicon or dendrite. After modified by phosphorus, the primary silicon of star-like and coarse platelet is changed to polygonal with less cute angles and decreasing average size. The eutectic silicon is also changed because it grows from the tip of angles......
(dendrite-like Al+ coarse Si flakes) is formed above the equilibrium temperature of eutectic(Al+Si) reaction(577℃).The coarse eutectic(CE) grains nucleate from the primary silicon particles formed earlier due to local enrichment of silicon solute and grow in a divorced mode between the dendritic Al phase and large silicon flakes.The fine eutectic(FE) grains nucleate later on other potential sites......
