dislocation glideの例文

例文モバイル版携帯版

  • Slip occurs by dislocation glide of either screw or edge dislocations within a slip plane.
  • In dislocation glide and at low temperatures, the dislocations are restricted to glide planes, or crystallographic planes across which the bonds are relatively weak.
  • For aluminum and other fcc materials with high SFE, dislocation glide is the main mechanism during cold rolling and the { 112 } ( copper ) and { 123 } ( S ) texture components ( copper-type textures ) are developed.
  • In contrast, in Cu 30 wt . % Zn ( alpha-brass ) and related metals and alloys with low SFE, mechanical twinning and shear banding occur together with dislocation glide as main deformation carriers, particularly at large plastic deformations.
  • Dislocation glide is the main process but cannot act on its own to produce large strains due to the effects of strain-hardening, where a dislocation  tangle can inhibit the movement of other dislocations, which then pile up behind the blocked ones causing the crystal to become difficult to deform.
