| Abstract: | The aim of this article is to investigate the effects of electromagnetic force on primary particle distribution of in-situ Al/Mg2Si functionally graded materials (FGMs) by electromagnetic separation method. Experimental results show that there is a critical value of electromagnetic force. The FGMs can be produced only when the electromagnetic force is beyond the critical value. With increasing the electromagnetic force, the particle volume fraction of the particle-packed regions increases, the length of the particle-packed regions decreases, the average gradient of particle volume fraction increases, and the primary particle size become smaller. |
