WebbAbstract A theory is presented with the intention of describing the internal stresses set up by slip processes in crystalline materials. It is based on the concept of dislocations as they occur in the mathematical theory of elasticity, and follows on the work of Volterra. Webb13 apr. 2024 · Theory of Dislocations provides unparalleled coverage of the fundamentals of dislocation theory, with applications to specific metal and ionic crystals. Rather than …

WebbMinority carrier recombination is studied in multicrystalline ingot cast silicon solar cells. The normalized recombination strength Γ of dislocations is obtained by correlating topograms of the internal quantum efficiency (IQE) with those of the dislocation density ρ.Γ is obtained by fitting an extended theory of Donolato to the experimental data.

Webb14 aug. 2009 · Since dislocations “multiply” as they move (i.e., they increase their length), and since they are almost always present initially in structural materials, their most important property is their mobility. If this is very small, as it is in covalently bonded crystals like silicon at temperatures below the Debye temperature (about 920 K in Si ... Webb22 maj 2016 · We investigate the mechanisms of incipient plasticity at low angle twist and asymmetric tilt boundaries in fcc metals. To observe plasticity of grain boundaries independently of the bulk plasticity, we simulate nanoindentation of bicrystals. On the low angle twist boundaries, the intrinsic grain boundary (GB) dislocation network deforms … Webb16 jan. 2024 · Theory of Dislocations - Kindle edition by Anderson, Peter M., Hirth, John P., Lothe, Jens.

Webb7 sep. 2024 · Below DBTT, screw dislocations have much lower mobility than edge dislocations, which appears to be the origin of brittleness. At DBTT, the dislocation mobility swings between brittle and ductile behavior; thus, two distinct characteristics of dislocations are observed at 70 °C in two separate tests ( Fig. 2 B and SI Appendix , Fig. … Webb13 apr. 2024 · Perez, Theory of Elasticity (Springer, 2024). do not alter the strain field of the current model. The equations of the linear elasticity are solved with the plane stress assumption because the lamellas are 150 nm thick; i.e., their thickness is much smaller than their width and height ( x and z directions, respectively).
