Semester

Fall
A unified treatment of kinetic processes in materials,including transport, chemical reactions, phase transformations, and microstructure evolution. Emphasis is placed on crystalline materials, but application to glasses, polymers and other material systems are discussed throughout. Specific topics include: kinetic theory of gases,rate theory, reaction kinetics, irreversible thermodynamics,diffusion in a broad spectrum of material classes (both atomistic mechanisms and phenomenological/continuum level models), influence of defects of diffusion, evolution of surfaces, phase transformations (solidification, nucleation and growth, spinodal decomposition), coarsening, grain growth, and morphological instabilities.

1. Irreversible Thermodynamics

Use the coupling between generalized forces (gradients of intensive thermodynamic variables) and generalized fluxes (of extensive thermodynamic variables) to predict the response of materials to changing conditions.

2. Rate Theory & Activated Processes

Apply the principles of rate theory (rate constants, equilibrium constants, etc.) and activated processes (energy barriers, etc.) to model various kinetic phenomena.

3. Diffusion

Describe diffusion mechanisms in various classes of materials and use appropriate models to make predictions.

4. Discontinuous Phase Transformations

Understand the mechanisms of discontinuous phase transformations (solidification, nucleation and growth, etc.), the characteristics of resulting microstructures, and be able to apply existing models for these kinetic phenomena.

5. Continuous Phase Transformation

Understand the mechanisms of continous phase transformation (spinodal decomposition, ordering, etc.), the characteristics of resulting microstructures, and be able to apply existing models for these kinetic phenomena.

6. Shape Evolution

Predict how the macroscopic shape and microstructure of materials will evolve under various conditions based on principles of driving forces and mechanisms of shape evolution (coarsening, grain growth, sintering, morphological instabilities, etc.).

7. Micro-to Macro-

Predict macroscopic (e.g. thermodynamics) behavior from models of atomic and/or microscopic phenomena and mechanisms.
