The stored energy due to dislocations is therefore given in general by an expres-sion of the form where E( 0) is a contribution from individual dislocations present in the volume between the dislocation boundaries. For medium and high stacking fault energy materials, this contribution is small.
The stored energy of plastic deformation has been estimated from transmission electron microscope measurements of dislocation boundary spacings and misorientation angles using Al (99.99 pct) cold rolled to reductions of 5 to 90 pct as an example system.
The stored energy can be measured by calorimetry, or it can be estimated through relationships between the stored energy and microstructural parameters or between the stored energy and flow stress.[1,2,3]The relationship between the stored energy (Es) and the deformation microstructure can be expressed by the equation
In the present study, the stored energy is calculated on a microstructural basis, using the misorientation angle distribution and surface area per unit volume of dislocation boundaries.

One can see that after a rapid initial growth this function reaches a (quasi-) steady-state plateau, and the stored energy is linear on the increment of the dislocation density Δ ρ = ρ ρ 0 when ρ ≫ ρ 0: (18) E s ≈ ε β 2 2 σ S (ρ ρ 0) = α G b 2 k 1 (ρ ρ 0)
