摘要：

The elastic energy contribution associated with a precipitation in beta arising from the lattice mismatch between the two crystal structures has been calculated and analyzed considering precipitates morphology, habit planes and spatial arrangement. The two first features have been determined for a single ellipsoidal precipitate solving the Eshelby inclusion problem by means of Fourier transforms. The spatial arrangement has then been investigated by computing the local stress-strain fields using fast Fourier transforms.
