Fig. Glissile Interstitial Loop Production in Cascades a.777 Diffraction of Electromagnetic Radiation from a Crystal with Charged Dislocations When the applied torque is balanced by the self-torque of the loop, we show how the solution can be obtained for the loop orientation, and how this orientation affects the glide force on the loop. The steady state flow stress, which is very low for this interaction process, depends mainly on the linear loop density and dislocation velocity and weakly on temperature. Dislocation Loop Glissile Dislocation Glissile Dislocation Loop These keywords were added by machine and not by the authors. The drag coefficient of a loop is determined for the first time, and is shown to be related to the diffusivity of clusters of interstitials via a model of dislocation â¦ A glissile dislocation loop with a burgers vector âbâ lying on a slip plane can expand or contract depending on the direction of the shear stress. 1 (a) A dislocation loop on a slip plane, and atomic arrangements at the core of (b) an -, (c) a -, and (d) a screw-dislocation in a sphalerite A small dislocation loop formed by the agglomeration of vacancies, that in its pure form cannot add much to plastic deformation, may transmutate into a dislocation loop bounded by a perfect Burgers vector (which in turn may split into Shockley partials) - it is now glissile â¦ In the other, drag of glissile interstitial loops with the same Burgers vector as the dislocation is considered for iron and copper. Wolfer WG(1), Okita T, Barnett DM. We derive here for the first time the equations that describe the combined motion and rotation of small prismatic dislocation loops in stress fields. tion loop by bowing out of an extended dislocation. Dislocation pinning by glissile interstitial loops in a nickel crystal: A molecular-dynamics study. One manner is that the glissile dislocation segment always bows in the original glide plane, as the conventional FR mecha-nism.Another is that noncoplanar composite dislocations ap-pear owing to conservative motion of polar dislocation seg-ments, and then bow out along each slip plane, creating a Molecular-dynamics simulations show that, in an embedded-atom method nickel crystal, interstitial loops made of <110> dumbbells may be absorbed by an edge dislocation in two different ways, either being attached to one of the Shockley partials by means of a dislocation junction or being transformed into a double superjog on the dislocation. This process is experimental and the keywords may be updated as the learning algorithm improves. ... glissile loop comes into contact with the edge dislocation. When the applied torque is balanced by the self-torque of the loop, we show how the solution can be obtained for the loop orientation, and how this orientation affects the glide force on the loopâ¦ Motion and rotation of small glissile dislocation loops in stress fields. In the case of an undecorated 1/2 loop, the dislocation does not enter a direct reaction because the 'easily' glissile loop moves away from the approaching dislocation.
