Crystallographic shear planes
Web(a–c), (e) are all at the same magnification with the shear plane horizontal. (d and g) are from a Transmission Electron Microscope foil made at a low angle to the shear plane, allowing the foil to intersect with features aligned within the shear plane several times. Grain sizes of <0.1 μm can clearly be seen in (d).

Webproduces extended planar defects, known as crystallographic shear planes (c.s.p.) (Bursill & Hyde I972a). In slightly reduced rutile TiO2x,' 0.002 < x < 0.02, the c.s.p. lie on {132}1 planes, and tend to cluster into pairs or larger lamnellae exhibi-ting characteristic c.s.p. spacings in the range 84 A 11, for a pair, to 38 A, in the WebThe configuration of the basis plane (0001) is shown in Fig. 1. The atoms of the "upper" plane are marked by the circles of bigger sizes, the atoms of the "low" plane - by the circles of less sizes. The direction of. advantageous shear, forming the planar defect in the basis planes, are < 12 3 0 > , in the prismatic planes - < 2203 > and < 1210 > .
