monokristalli või polükristalli terasisene nihe, mis on tingitud dislokatsioonide nn konservatiivsest liikumisest libisemistasanditel (vt libisemistasand; vrd teradevaheline libisemine, dislokatsioonide mittekonservatiivne libisemine), the process involved in the plastic deformation of metal crystals in which the change in shape is produced by parts of the crystals sliding with respect to each other along certain crystallographic planes, slip planes (see: slip plane; compare: grain-boundary sliding, dislocation climb)
