Abstract
The lattices of the components of a classical twin are always inclined to one another at a definite angle and are rigidly joined at the surface of contact. The indices of the twin plane, the direction of twinning, and the twinning axis are small and are determined by the crystal structure. When crystals are mechanically stressed, reorientation of large regions of the lattice can occur as well as classical mechanical twinning and plastic deformation by slip; the orientation of these regions does not obey the rules of classical twinning. The angle through which the lattice is rotated depends both on the crystal structure and on the extent of the deformation. The plane of junction has a large (irrational, see § 1.3) index, and in general is not a plane of symmetry of the adjacent crystals. In individual cases the lattices are joined symmetrically along irrational planes of contact.
