Through the morphological observation on silicon particles of Al-Si-Cu-Mg cast alloy, it is found, that during solution heat treatment the evolution of eutectic silicon morphology and their effect on mechanical property can be classified into three stages. In the initial stage, necking, stubbing and fragmentation of silicon particles results in an improvement in plasticity of the alloy. In the intermediate stage, the mechanical properties of the alloy attain peak values due to the spheroidization of silicon particles.
