ABSTRACTThis paper presents a new experimental method to investigate solid-liquid interface morphologies during Zone-Melting-Recrystallization at lower than the typical processing temperatures. Gallium films were used as a substitute for silicon films. In situ preliminary investigation identified three phenomena typically occurring during ZMR of silicon films: a) Transition from planar to dendritic to cellular morphologies was observed for different processing conditions; b) cell period proved to be dependant on scanning velocity; c) instabilities at the solidification interface at low heating strip temperatures were caused by supercooling and optical property variations as the material changed phase.

In situ observation of growth process of high temperature phase in 0.15% C carbon steel during solidification concerned with using Confocal Scanning Laser Microscope (CSLM), the growth rate of -phase has been measured. The results indicate that high temperature -phase grows at cell crystal way when the cooling speed reaches 2°C/min in 0.15% C carbon steel. The -phase of round or oval cross-sectional shaped may grow stably. The growth rate of -phase is gradually getting slow along with increasing of curvature radius. The variation of growth speed tends to be similar with different solid-liquid interface shapes of -phase. The growth rate of concave solid-liquid interface is faster than that of convex solid-liquid interface for phase. The smaller radius of curvature of phase is, the faster the growth rate reaches.

The δ-phase growth process of Fe-0.2%C-0.6%Mn steel during solidification was in-situ observed using Confocal Scanning Laser Microscope (CSLM). The effects of shape of solid/liquid interface on the growth rate were investigated. The results indicate the growth rate of concave-shaped solid/liquid interface is faster than that of convex-shaped solid/liquid interface at the beginning of δ-phase growth. The two kinds of growth rates decreased both and approached to the same gradually as the solidification continues. The intrinsic reasons were discussed in detail.
