Abstract:

A quantitative phase-field model for the evolution of polycrystalline structures is presented. The model is able to treat concurrently grain growth, Ostwald ripening and growth driven by the relative stabilities of the bulk phases. The model allows the specification of energy and mobility for each interface individually. Simulation results are discussed for 3 industrially relevant applications, namely grain growth in the presence of second-phase particles, anisotropic grain growth in systems with a fiber texture and diffusion and coarsening of lead-free solder joints.
