Grain size distribution under simultaneous grain boundary migration and grain rotation in two dimensions

Grain rotation mediated by grain boundary dislocations in nanocrystalline platinum

Grain rotation is a well-known phenomenon during high (homologous) temperature deformation and recrystallization of polycrystalline materials. In recent years, grain rotation has also been proposed as a plasticity mechanism at low temperatures (for example, room temperature for metals), especially for nanocrystalline grains with diameter d less than ~15 nm. Here, in tensile-loaded Pt thin films...

Five-parameter grain boundary distribution in grain boundary engineered brass

We report the first application of a five-parameter determination of grain boundary types to grain boundary engineered alpha-brass. The most important findings were that the distribution of planes showed a prevalence of <110> tilt boundaries, especially asymmetric tilt types, and the presence of <111> twist boundaries. This distribution resulted from the low energy of these boundary types.

Grain boundary planes: New dimensions in the grain boundary character distribution

The five parameter grain boundary character distribution quantifies the relative areas of different types of grain boundaries, distinguished by their lattice misorientation and grain boundary plane orientation. The viewpoint presented in this paper is that this distribution is a sensitive metric of polycrystalline structure that can be related to macroscopic properties. To demonstrate the influ...
