The change of the strain energy density in the different crystal planes of the cubical γ phase occurs during creep at high temperature, and the cubical γ phase in the alloy is directionally grown along the crystal plane with bigger strain energy. Then, the change of the atomic potential energy, interfacial energy and lattice misfit stress is thought to be the driving force for promoting the elements diffusion and directional coarsening of γ phase. Coefficient of the finite element formula for determining the use of traditional methods is not good, this innovative combination of the advantages of genetic algorithm to determine coefficients, and then using the finite element simulation tool shown to be correct.
