英文摘要	Microstructural evolution during partial remelting of AM60B alloy refined by 0.2 wt.% SiC particles at 615 degrees C has been investigated. The effect of as-cast microstructure on the resulting semisolid microstructure has also been discussed. The results indicate that the evolution process includes five stages, initial rapid coarsening, structure separation, spheroidization and coarsening, partial melting and final coarsening. The finer the as-cast microstructure is, the smaller and more spheroidal the primary particles of the resulting semisolid microstructure are. There is a threshold for the grain size of the as-cast microstructure. When the grain size is about 100 gm, one dendrite frequently evolves into one primary particle after being partially remelted. But when the grain size is larger than 100 mu m, one dendrite often separates into several particles, and when it is smaller than 100 mu m, one primary particle always originates from several dendrites.
