Static recovery process creates a change in the stored energy inside the crystal grains. It is assumed that point defects and dislocations in movement and other factors result in reduced energy storage inside grains; and because of high dislocation density in the grain boundary regions, their stored energy is twice as much as that within the grains; meanwhile, the dislocation tangle in the triple junctions gives rise in stored energy that is 2.5 times as muchh as the energy storage within the grains.
Considering the fact that the dislocation density distribution near the grain boundary has a certain range, the stored energy on both sides of the grain boundary is higher than that in the central region of grains. So the stored energy within the small grains is higher than within large grains
