摘要：The influence of Si content and pulsed magnetic filed parameters on the solidification structure of the Al-Si binary alloy was investigated. Experimental results indicated that the addition of Si has a significant refinement on the macrostructure of the commercial pure aluminum. The grain size of the Al-Si binary alloy decreases first and then increases with increasing of Si content which could be caused by the constitutional-supercooling, but for the case where a PMF was applied, the grain size was further refined compared with as-cast state.
