Sentence examples for migration of grains from inspiring English sources
In addition, we impose the inequality α > γ(β − 1) because the migration of grains is faster on a stoss side than it is on the corresponding lee slope (see Eq. (2) for the gentlest lee slope).
We present a molecular dynamics simulation study of the migration of grain boundaries with triple junctions.
In both cases, a large amount of atomic shuffling is needed to account for the migration of grain boundaries.
It yields the same result for the migration of grain boundaries but a different result for phase transformations.
Experimental analysis has indicated that driving force for the formation of cellular precipitates could be resulted from the chemical instability of supersaturation after annealing and migration of grain boundaries, and this phenomenon could be suppressed either through alloy design to increase gamma-prime solvus, and to hinder the migration of grain boundaries.
The migration of grain boundaries during annealing is quantified using the SPM measurements of surface topography of the regions swept by migrating grain boundaries.
Until now, this coarsening has been analysed in terms of classic LSW theory or in terms of the migration of grain boundary liquid films.
The activation energy for the flow stress response suggests that deformation is largely accommodated by sliding and migration of grain boundaries.
We postulate that such transport is mediated by migration of grain boundary disconnections containing charged jogs, rather than by jumping of isolated point defects in random high-angle grain boundaries.
Theoretical models are suggested that describe the effects of stress-driven migration of grain boundaries (GBs) on both the formation of nanoscale cracks (nanocracks) and the growth of comparatively large cracks in deformed nanocrystalline ceramics and metals.
Experimental results indicate that although fraction of non-twin type Σ3 special boundaries could be increased by multiple-cycles of thermomechanical processes, the presence of Ti(C, N) hindered the migration of grain boundary, and affected both grain size and special boundary formation.
