Role of grain boundary plane in grain boundary engineering

Materials Science and Technology, 2010
There is an increasing amount of interest in grain boundary engineering (GBE) to improve the properties of the grain boundary network. In general, research has concentrated on use of a grain boundary misorientation based approach, namely, the coincidence site lattice (CSL), to categorise ‘special’ boundaries.

Grain boundary inhomogeneity and grain boundary heterodiffusion

Philosophical Magazine A, 1995
It is shown that the inhomogeneity of the grain boundary (GB) i.e. the effect of the distribution of different lattice sites on the heats of interaction with species, leads to nonlinear GB penetration plots (in Fisher's coordinates). The sign of curvature and the values of deviation from a straight concentration profile depend on the interaction ...

EVOLUTION OF GRAIN BOUNDARIES

Mathematical Models and Methods in Applied Sciences, 2001
Evolution and trend to equilibrium of a (planar) network of grain boundaries subject to curvature driven growth is established under the assumption that the system is initially close to some equilibrium configuration. Curvature driven growth is the primary mechanism in processing polycrystalline materials to achieve desired texture, ductility ...

Grain Boundary Sliding at Serrated Grain Boundaries

Advanced Performance Materials, 1997
A constitutive model is developed for grain boundary sliding (GBS) at serrated grain boundaries. Based on a previously developed GBS model, using the dynamics of grain boundary dislocation pile-up, the present model takes the average of the sliding rate over the characteristic dimensions of grain boundary serrations.

Grain boundary segregation and grain-boundary heterodiffusion

Philosophical Magazine A, 1992
Abstract It is shown that nonlinear segregation effects (saturation, interaction of species) lead to nonlinear grain-boundary penetration plots. If the diffusion penetration depth is larger than a critical value, the concentration profiles become linear.

Grain Boundary Grooving as an Indicator of Grain Boundary Phase Transformations

Interface Science, 2001
The atomic force microscopy (AFM) was used to study the grain boundary (GB) groove profiles far away from the melting temperature T m. It is shown that AFM allows one to measure the temperature dependence of the GB energy in a rather broad temperature interval (from 0.85 T m to T m). The GB energy and GB segregation of Bi were measured at 1123 K in the
