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.
