Grain boundaries in twist bicrystals grown by the Kyropoulos technique were examined by: (1) pulling the crystals apart at the grain boundary, and (2) polishing away one side of the bicrystal to within 0.5 mm of the grain boundary and examining the grain boundary surface by focusing through the layer of NaCl. Both of these techniques showed that the bicrystals were held together by small regions or pips of continuity across the grain boundary. The small bonded regions are separated by large unbonded areas. The pip density ranged from 500 to 20,000 cm−2 for 45° and 10° twist bicrystals, respectively.
