Effect of Crack Geometry on Dislocation Nucleation and Cleavage Thresholds
A continuum model based upon the Peierls-Nabarro description of a dislocation ahead of a crack is used to evaluate the critical mode I loading for dislocation nucleation at the tip of a finite, pre-blunted crack. A similar approach is used to evaluate the critical mode I loading for atomic decohesion. Results are presented for various crack tip root radii (a measure of bluntness), for several c...
متن کاملDislocation Nucleation at Metal-ceramic Interfaces
Ab~act-The ductile vs brittle behaviour of metal-ceramic interfaces is discussed within an atomistic framework, in which the mechanical response of an interfucial crack is assumed to be ultimately controlled by the competition between atomic decohesion and dislocation nucleation ahead of the crack tip. As in later versions of the Rice-Thomson model, this competition may be evaluated in terms of...
متن کاملDislocation nucleation in bcc Ta single crystals studied by nanoindentation
The study of dislocation nucleation in close-packed metals by nanoindentation has recently attracted much interest. Here, we address the peculiarities of the incipient plasticity in body centered cubic bcc metals using low index Ta single crystals as a model system. The combination of nanoindentation with high-resolution atomic force microscopy provides us with experimental atomic-scale informa...
متن کاملAn Energy Balance Criterion for Nanoindentation-Induced Single and Multiple Dislocation Events
Small volume deformation can produce two types of plastic instability events. The first involves dislocation nucleation as a dislocation by dislocation event and occurs in nanoparticles or bulk single crystals deformed by atomic force microscopy or small nanoindenter forces. For the second instability event, this involves larger scale nanocontacts into single crystals or their films wherein mul...
متن کاملMorphology optimization of MOCVD-grown GaN nucleation layers by the multistep technique
The heteroepitaxial growth of gallium nitride (GaN) on sapphire substrates by metal-organic chemical vapor deposition is most commonly carried out using the two-step growth process. This process involves the deposition of a thin GaN nucleation layer (NL) at a temperature of approximately 450–600 1C. The morphology of this low-temperature film after annealing is known to have a crucial effect on...
