Stress and Strain Fields Calculations Associated with the Formation of Intragranular α Precipitates

摘要：

The elastic energy contribution associated with α precipitation in β 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.
