Modification of a Hypereutectic Aluminium Silicon Alloy under the Influence of Intensive Melt Shearing

Abstract:

A physical modification method with the application of intensive melt shearing during solidification was used to treat a hypereutectic aluminium silicon alloy. The effect of intensive melt shearing on the microstructure of the alloy was studied. Experimental results showed that intensive melt shearing can significantly refine the primary silicon particles, and treatment temperature plays a very important role in the refinement. The optimum condition for refining primary silicon particles of Al-20wt%Si alloy is treating at 660 °C.
