Hence, a surface such as a boundary impedes the motion of a dislocation along
its entire slip plane length, and this provides a greater resistance to slip than
isolated point obstacles lying in the slip plane. Grain boundaries are particularly ...
Grain boundary Slip plane (a) (b) FIGURE 11.10 Heterogeneous plastic flow via
slip bands or (in the case illustrated) planes can lead to cavity formation at grain
boundaries. In (a) slip leads to an offset (ledge) at the grain boundary.
11.14a is appropriate when surface diffusion is rapid in comparison to grain-
boundary diffusion. This enables the void to maintain its spherical geometry as it
grows (a sphere has the lowest surface area per unit volume). When the opposite

This book is very confusing and not clear about anything, which is the worst point.
It lacks depth. Described a lot, but not in a effective manner.
It seems like just a manual as It hardly talks about the mathematical formulation.
Also, it is exhausting and very time consuming to read and after finishing I get confused.
Right now, I usually roam internet to understand a topic rather than reading it.
However I am just a PhD student, its all from my perspective.
