Hooke's law gives the local elastic stress as σ el ij(r)=Cijklε el kl(r), and the local elastic constants Cijkl is assumed to be Cijkl={1-h(φi)}Cm ijkl+h(φi)Cpijkl, where Cm ijkl and Cp ijkl represent the elastic constants of the γ matrix and the γ' precipitate, respectively.
The equilibrium elastic field is determined by solving the local mechanical equilibrium equation, i.e., ∂σ el ij/∂ rj = 0.

Our numerical estimations show that in the case of steel the values of E el vary between 10 4 J/m 3 and 10 6 J/m 3.
Our main conclusion is that the orientations with minimum E el values have maximum E pl energy.
The grains with low values of E el fit better to the neighbouring material than other grains.
Our main observation is that the E pl maxima coincide with E el in the crystal orientation space.
