“…The regenerated initial microstructure in the Monte Carlo simulation was allowed to coarsen using Taylor factors as the driving force for grain growth in addition to capillary driving forces from the grain boundaries. [21] The grain boundary mobility function in Figure 9(b) was based on the work by Viswanathan and Bauer. Figure 2 The presence of second-phase particles or the existence of grains much larger than the average may interfere with normal grain growth.…”

“…(1) represents the energy of individual dislocations, and the second term 0 ln͑͒ is due to the interactions between the dislocations. It is believed and also experimentally observed in some 3D systems [14] that this result is valid not only for small-angle GBs but also for large-angle ones, although its theoretical justification is questionable. In the current experiment, was measured up to 30°and the small-angle approximation will be assumed.…”

Two-dimensional (2D) colloids embedded in a soap film are employed to study the structures and dynamics of grain boundaries (GBs). While a soap film is drawn vertically from a concentrated bulk suspension, the colloidal particles self-assemble to form polycrystalline structures with a typical grain size of about 100 lattice spaces. Studies of these grain boundaries reveal that the GB lines are faceted at "atomic" scale, leading to a constant energy per unit length along each line. The measured GB energy as a function of misfit angle is in agreement with Reed-Shockley's theoretical predictions. When an external mechanical vibration is applied to the bulk suspension, the grain boundaries are observed to migrate and grains to rotate under the stress field induced by the vibration. The total length of the grain boundaries is found to diminish logarithmically with time, with the rate constant being a function of the excitation strength. This phenomenon, called "mechanical annealing," provides a robust means to grow large 2D single-domain crystals.

“…A number of investigators have shown that the interfacial energy incr eased to maximum values with increased difference in angular orientation between pairs of crystals for angles ranging from 12 0 for tin [10] to 29. 0 for an iron-silicon alloy [11 ]. If the grain-boundary energy, and therefore the chemical ac tivity of grain boundaries in alpha brass, incr eases with incr eased difference in orientation of adjacent grains, it is to be expected that the probability that a stress-corrosion crack would develop at a particular grain boundary would depend on the relative orientation (or degree of misfit) of the crystals meeting at that boundary.…”

The cr ystallographic planes bounding intercrystalline stress corrosion cracks in two large-grained Alpha brasses and those followecl by t ranscrystalline st ress-corros ion cracks in large-grained beta brass were determined b y X-ray diffract ion m cthods . Intercr ystalline stress-co rrosiOD cracking in t he alpha brasses originated bet weeD grains t hat, because of their relative orientatioD, had high iDterfacial e nm·gy contents. It is the relative orie ntation, Dot the cr ystallographic type, that de termines the s usceptibility to strcss-corrosion cracki ng of alpha brass in grain boundaries approximately Dormal to t he appli ed stress. Transcryst alline st ress-corrosion cracking of beta brass occu rred in grai ns t ha t were orie nte d m ost favorably for slip, and in plancs t hat were appro xi ma tely normal to t hc applied stress. No plane or famil y of planes in beta brass was found to bc pa rtic ularly s usceptiblc to stres3-corrosion cr acking. It is post ulated that in each case cracking progresscd by a film ruptu re mechanism .
