초록

The semisolid processing of two Al-Si alloys, A356 and Al-25wt%Si, was studied with using the rotor composed of permanent magnets. The semisolid slurry was agitated by the electromagnetic force induced from the rotating permant magnets. The round shaped primary ${\alpha}$ phases were formed in A356 alloy as a result of agitation. In Al25wt%Si alloy, spherodization of primary Si particles was not observed with the rotation of the magnets. The primary Si particles were segregated to the outer surface area of sample, which became pronounced with increasing the rotating speed of magnets.
