Notes:
The symmetry group of the coincidence site lattice (CSL) is used for the study of the properties of triple junctions formed by plane boundaries. The experimental evidence that there are junctions with an obviously symmetrical relationship among the adjacent planes is analysed systematically. The analysis concerns the triple junctions in which the grain boundaries (GBs) are described by 180° CSL rotations. For these triple junctions the common intersection is a CSL rotation axis of the three GBs. Two cases need to be distinguished. In the first case the common intersection is a symmetry axis of the three CSLs, while in the second case the common intersection is a general direction. Thus in the first case the corresponding symmetry element is a common symmetry element of the three CSLs participating in the junction.
