WebThe Burgers vector of the dislocation line bounding the collapsed sheet is normal to the plane with b = a 3 [1 1 1], where a is the lattice parameter, and such a dislocation is sessile since it encloses an area of stacking fault which cannot move with the dislocation. A Frank sessile dislocation loop can also be produced by inserting an extra ... http://dtrinkle.matse.illinois.edu/MatSE584/kap_5/backbone/r5_4_2.html
For FCC crystals, Thompson tetrahedrons or Thompson notation are an invented notation for more easily describing partial dislocations. In a given unit cell, mark point A at the origin, point B at a/2 [110], point C at a/2[011], and point D at a/2[101]--these points form the vertices of a tetrahedron. Then, mark the … See more In materials science, a partial dislocation is a decomposed form of dislocation that occurs within a crystalline material. An extended dislocation is a dislocation that has dissociated into a pair of partial dislocations. The … See more Frank partial dislocations are sessile (immobile), but can move by diffusion of atoms. In FCC systems, Frank partials are given by: See more The Lomer-Cottrell dislocation forms via a more complex dislocation reaction. For example, consider two extended dislocations: DB = Dγ + γB and BC = Bδ + δC. When they meet, it is more energetically favorable to form a single dislocation, DC = … See more A dislocation will decompose into partial dislocations if the energy state of the sum of the partials is less than the energy state of the original dislocation. This is summarized by … See more Shockley partial dislocations generally refer to a pair of dislocations which can lead to the presence of stacking faults. This pair of partial dislocations can enable dislocation motion by allowing an alternate path for atomic motion. See more When forming stacking faults, the partial dislocations reach an equilibrium when the repulsive energy between partial dislocations matches the attractive energy of the stacking fault. This means that higher stacking fault energy materials, i.e. those with high … See more WebJan 1, 1970 · faults is generally called a partial dislocation. Frank (1951 b) and Frank and .
