An analytical solution for shape evolution of a coherent misfit precipitate in triaxially stressed solid has been proposed based on Eshelby inclusion theory. With complete energy consideration, the free energy that controls the shape evolution of the precipitate is a function of the precipitate shape, size, triaxially applied stresses, misfit strains, and Young’s moduli of the precipitate and the matrix. Based on the energy analysis, a comprehensive picture of shape evolution of the precipitate is presented.
