Engulfment behavior was observed in situ using transparent organic materials and the critical growth velocities were determined. The critical growth velocity of the SCN-acetone alloys increased with increasing temperature gradient and decreasing alloy concentration, while that of the salol-acetone alloys was independent of temprature gradient. Not only the interfacial energies but also the interface shape and morphology contribute to the engulfment/pushing behavior. The present result suggests that conventional alloys show the engulfment behavior of inclusions/insoluble particles as well as the organic alloys.
