Chapter 4
http://users.encs.concordia.ca
It is convenient to divide grain boundaries into those whose misorientation is greater than a certain angle – high angle grain boundaries (HAGB), and those ...
Grain boundary
https://en.wikipedia.org
The movement of high-angle boundaries occurs by the transfer of atoms between the neighbouring grains. The ease with which this can occur will depend on the ...
Grain boundary characterization
https://www.mpie.de
Grain boundaries are characterized by 5 rotational and 3 translational parameters. All these parameters influence the properties of boundaries.
Grain boundary maps (low and high angle ...

... boundaries between 2 • < ϑ < 15 • are considered the low angle boundary, while those with ϑ > 15 • are assumed to be high angle boundaries [14]. In Figure 6 ...
High Angle Boundary
https://www.sciencedirect.com
High-angle boundaries are best treated as small deviations from the nearest CSL. They are then similar to low-angle boundaries that are a small deviation from ...
High
https://www.sciencedirect.com
Many high-angle grain boundaries can be regarded formally as superposed arrays of dislocations spaced atomic distances apart.
Subgrain Boundaries

In contrast the properties of high-angle grain boundaries, whose misorientation is greater than about 15 degrees, are normally found to be independent of the ...

Young's modulus and hardness are higher in sample with low angle grain boundaries, while creep length is larger in sample with high angle ones.
