Abstract

Preliminary results on the application of the finite element method to the determination of nucleation energetics in solid-solid phase transformations are presented. A Landau-Ginzburg type potential is used to describe the material response. The underlying Landau potential is taken to be of the 2-3-4 type and the gradient energy contribution is taken to be quadratic. The problem of homogeneous coherent nucleation of a spherical particle in an infinite matrix as a function of both mechanical and chemical driving force is considered. The present nonlinear model exhibits many of the physical phenomena associated with spinodal decomposition.
