(a) The surface energy will be greater than the grain boundary energy. For grain boundaries, some atoms on one side of a boundary will bond to atoms on the other side; such is not the case for surface atoms. Therefore, there will be fewer unsatisfied bonds along a grain boundary.

Would you expect the surface energy to be greater than the same as or less than the grain boundary energy Why?
As we know, the lack of bonds between atoms leads to the energy surface rise. Therefore the surface energy is greater than boundary energy.
What is grain boundary energy?
Grain boundaries are defects that have an excess free energy per unit area. This is evident by the fact that during most thermal and chemical etching processes, material near the grain boundary is preferentially removed.
Why is surface energy greater than grain boundary?
In the other words, surface atoms have fever bounds than atoms along the grain boundary. As we know, the lack of bonds between atoms leads to the energy surface rise. Therefore the surface energy is greater than boundary energy.
Which grain boundary has a lower energy?
The results clearly show that the boundaries enriched with Nd have a lower average energy than those with less Nd. One question is why the complexion transition nucleates at some grain boundaries, but not at all boundaries.
Would you expect the grain boundary energy of a small angle grain boundary to be greater than the same as or less than a high-angle one?
The grain boundary energy of a small-angle grain boundary is less than for a high-angle one.
How do grain boundaries affect conductivity?
A grain boundary (GB) is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material.
Is surface energy greater than grain boundary?
(a) The surface energy will be greater than the grain boundary energy. For grain boundaries, some atoms on one side of a boundary will bond to atoms on the other side; such is not the case for surface atoms. Therefore, there will be fewer unsatisfied bonds along a grain boundary.
Why are grain boundaries in a higher energy state?
The mismatch of the orientation of neighboring grains leads to a less efficient atomic packing within the grain boundary. Hence the atoms in the boundary have a less ordered structure and a slightly higher internal energy.

The surface energy for a crystallographic plane will depend on its packing density [i.e., the planar density (Section 3.11)]—that is, the higher the packing den sity, the greater the number of nearest-neighbor atoms, and the more atomic bonds in that plane that are satisfied, and, consequently, the lower the surface energy. From the

Greater- The surface energy will be greater for an FCC (100) plane than for a(111) plane because the (111) plane is more densely packed(i.e., has more nearest neighbor atoms in the plane); as a result, more atomic bonds will be satisfied for the (111) plane, giving rise to a lower surface energy.
