The Morphological Stability of Internal Melting Figures in Ice
Abstract Wavy perturbations formed on disc-shaped internal melting figures in ice were observed. It was found that a minimum wavelength of the perturbations was approximately 100 μ m and a critical thickness of the figures for the formation of the perturbations was 10 μ.m. The critical thickness did...

Abstract Wavy perturbations formed on disc-shaped internal melting figures in ice were observed.

A minimum wave number of the perturbation was 6 and the axis of its sixfold symmetry was parallel to the <11 2 0> direction, The perturbations with large wave number were formed on the inclined side faces of internal melting figures of which the shape was like a truncated cone.
