Stress field of a system of two misfitting spherical precipitate particles
- Michigan Technological Univ., Houghton (USA)
An integrodifferential equation has been solved by numerical methods to determine the stress fields inside and outside of two spherical isotropic precipitate particles in an isotropic matrix. It is well known that for a single spherical particle, with a dilatational type transformation strain, there is no hydrostatic component to the resulting stress field in the matrix. For the case of two inhomogeneous precipitates, with dilatational type transformation strains, the mutual interactions between precipitates is found to produce a hydrostatic component of stress in the matrix. The stress field of two misfitting precipitates can in turn either enrich or deplete the solute concentration in the surrounding matrix, depending on the sign of the misfit and the ratio of the precipitate to matrix elastic constants.
