Grain boundary dislocations and steps may have a major role in migration. The perfect grain boundary dislocations discussed in the present work can have steps at their cores and the step height depends on the dislocation and the boundary concerned. A model for migration is developed and it is correspondingly sensitive to the …

WebSep 25, 1997 · The motion of 〈101̄0〉/θ ice grain boundaries is studied using the “Sun−Bauer” technique. The samples were annealed at temperatures between −2 °C and −20 °C, for times up to 1400 h, and Mγ values for mixed and tilt boundaries were determined (M and γ are the mobility and the excess of free energy per unit area of the grain … Web1 hour ago · Installing CCTV cameras, restricting entry of outsiders, hiring private security and increasing the height of boundary walls -- these were among the measures …
WebSep 24, 2006 · The characteristic times associated with each type of event decreases with increasing driving force for boundary migration. We present evidence as to how the driving force biases these types of events, leading to boundary migration. While the string-like atomic motion is an intrinsic feature of grain boundary dynamics and is important for … WebJun 1, 1994 · Some of the migrating grain boundaries reverse their directions. The specimen heat treated in vacuum do not show any change of the grain boundary structure. The diffusion of C is thus shown to induce the grain boundary migration and recrystallization in Ni at three temperatures.
WebNov 24, 2024 · A nanolaminated surface layer was produced on interstitial-free steel by surface mechanical rolling treatment. While the microstructure showed relatively high thermal stability during annealing at 500°C, significant grain boundary (GB) migration occurred in the nanolaminated surface layer during chromizing at the same temperature.
