The results show that the inclusion particles move through the liquid channels formed by the remaining solid. The average movement rate is 80 μm/s when the volume fraction of remaining austenite is about 70 %. Near to absolute melting, the movement rate of the inclusion far away from S-L interface is higher than 1500 μm/s, and that nearby the interface is in the range from 50 μm/s to 200 μm/s. A metal layer (δ ferrite phase) has been observed on the melt surface. It has the crystal boundary and sub-boundary similar to ordinary metal. The inclusions have been adsorbed by the metal layer. The morphology of the visible inclusion transfers from granular to worm-like during melting. The inclusions attract severely with each other, as a result, they agglomerate and granulate close-by the metal layer.
