Aug 1, 1982 · 1 CSL/DSC LATTICE MODEL FOR GRAIN BOUNDARIES AND THEIR LINE DEFECTS IN CUBIC MATERIALS 2.1 Description of basic model The well known CSL/DSC Lattice model [1-4] has met with considerable success in describing the equi- librium structure of grain boundaries in cubic materials.

Mar 1, 2019 · The DSC lattice, shown in Fig. 2 in cyan, is the sparsest lattice that includes all points of crystal Lattices 1 and 2 on both sides of the grain boundary. A feature of the DSC lattice is that it enumerates the set of allowable shifts that maintain a given CSL.

The set of all possible displacement vectors which preserve the CSL defines a new kind of lattice, the so-called DSC-lattice. The abbreviation "DSC" stands for "Displacement Shift Complete", not the best of possible names, but time-honored by now.

The set of all possible displacement vectors can be expressed as the translation vectors in a new kind of lattice, the "Complete Pattern Shift Lattice", abbreviated by Bollmann as " DSC lattice", that we encountered earlier (in a much simpler form).

This paper shows how the 0 lattice approach to the determination of CSL and DSC lattices may be simplified by numerical techniques and derives such lattices for hexagonal materials. In addition the symmetries available in the hexagonal lattice are …

The general CSL/DSC Lattice model for internal boundaries in crystalline materials is described. The model is essentially a 'fit-misfit' model in which the regions of 'fit' are patches where partial lattice matching across the boundary is achieved and the regions of 'misfit' are boundary line defects possessing dislocation/boundary step character.

Aug 25, 2015 · Here we show that the GB displacement shift complete (DSC) dislocation mechanism for GB shear coupled migration is still functioning even if the geometry orientation of the GBs deviates a...

May 19, 2021 · We analyze the dislocation content of grain boundary (GB) phase junctions, i.e., line defects separating two different GB phases coexisting on the same GB plane.

Nov 1, 1974 · The shifts of lattice 2 for which the second alternative holds form a lattice, which is known as the DSC lattice. Its vectors are the geometrically possible Burgers vectors of grain boundary dislocations, which correct for small devia- tions from the coincidence orientation.
