Grain-Boundary Energy and Grain-Boundary Groove Angles in Ice
Abstract Relative grain-boundary energies in ice were measured as a function of mismatch angles made by the c -axes or a -axes in grains, using ice specimens having triple grain boundaries. It was found that the Read–Shockley equation for grain-boundary energy was valid for grain boundaries tilted b...

| Summary: | Abstract Relative grain-boundary energies in ice were measured as a function of mismatch angles made by the c -axes or a -axes in grains, using ice specimens having triple grain boundaries. It was found that the Read–Shockley equation for grain-boundary energy was valid for grain boundaries tilted between 0° and 15°. Angles of the solid–vapour grain-boundary groove in ice were measured by the use of micro-interferometry at grain-boundary grooves covered with extremely thin metalic foil. The data were compared with those measured by a silvered replica of grain-boundary grooves. |
