Transport of heat and mass,d material sciences. In liquids heat and mass can be transported by diffusion, convection, or both. To describe the diffusion process we derive the conservation equations for heat and mass under diffusive and convective-diffusive conditions. These basic equations are later used for particle growth and coarsening.

Introduction,nd phase nucleates, grows, and coarsens. Nucleation of the second phase occurs since the energy of the single phase system can be reduced by forming regions of the second phase. Nanometer-sized precipitates of the new phase thus appear. Growth of nuclei then proceeds due to heat diffusion away from

Thermodynamics of alloys,of particles embedded in a matrix. The reader who is already familiar with the concepts of free energy, chemical potential, equilibrium of heterogeneous alloys, the Gibbs-Thomson effect etc. may skip this chapter.

Growth,cooled melt, second growth in a supersaturated matrix, and third growth by interface kinetics of first order where mass or heat is transported. We then discuss the growth by interface kinetics of second order and growth of particles or droplets where convective heat or mass fluxes play an important
