WebA Frank-Reed source permits the dislocation multiplication required for slip in crystalline solids. The sequence of source operation is shown and results in the shedding of a dislocation loop and regeneration of a dislocation that can repeat the sequence. In the absence of a stress field a dislocation will straight (a). WebThe mechanism by which dislocations are generated (multiplied) was proposed by Frank and Read in the 1950s and is known as the Frank-Read source. …. When a tensile stress is applied to a single crystal, the shear stress exerts a force F = *b on the dislocation line, which is pinned at both ends.
WebMay 20, 2024 · A total of ten Frank–Read sources were observed at a different stage of straining (Supplemental Figures S7–S14). These dislocations typically glide toward … WebIn materials science, a Frank-Read source is a mechanism explaining the generation of multiple dislocations in specific well-spaced slip planes in crystals when they are …
WebSep 27, 2006 · The conditions necessary for successful Frank-Read source operation are discussed. In the microstrain region the source dislocations are predicted to form loops elongated along the screw direction. Experiments on the ‘partial reversibility’ of the yield stress with temperature are described; it is shown that β is not reversible, but that ...
