Abstract
The deformation ofα-SiC single crystals in bending with the direction of extension and compression approximately parallel to the basal face (the axis of bending parallel to (0001), T = 2000–2100°C) involves slip over the basal plane; the directions of slip are and . Accordingly, crystallographic planes rotate about parallel axes, and . Slip in the direction may be a consequence of migration of dislocations with Burgers vectors equal to b=2/3 (a full dislocation and\(\overrightarrow b = 1/3\) (a partial dislocation). X-ray microdiffraction observations show [12] that partial dislocations with Burgers vector components parallel to [101¯1] frequently form inα-SiC; travel of partial dislocations apparently plays an important part in the deformation of α-SiC. The deformation ofα-SiC is accompanied by kink band formation [1].
