“…Our model incorporates the concept of densification developed in the stereological theory of sintering (DeHoff, 1989). In this approach, the densification mechanism comprises vacancy migration from pores to grain boundaries and vacancy annihilation at the grain boundaries.…”

“…Rather than shrink pores, as Hassold et al (1990) did, we simulate the formation, diffusion, and annihilation of vacancies. A vacancy annihilation mechanism based on the view developed in the stereological theory of sintering (DeHoff, 1989) is added to the model in order to simulate densification. This mechanism comprises vacancy migration from the pores to grain boundaries and vacancy annihilation at the boundaries.…”

“…The densification of material in simulation is achieved by vacancy annihilation (Braginsky et al, 2005). In DeHoff's stereological theory of sintering densification (DeHoff et al, 1989), the densification mechanism comprises vacancy migration from pores to grain boundaries and vacancy annihilation at the grain boundaries. The densification is the process of vacancies being painted on the grain boundary, with an entire monolayer of vacancies annihilated, so that the mass centers of adjacent grains move towards the grain boundary.…”

Structure is at the heart of the materials science paradigm connecting processing with properties. In the hierarchy of structures that exist in materials microstructure offers the richest variety of structural arrangements. This variety is often conveniently accessible, e.g., simply by heat treatment or mechanical deformation. Exploration of the relation between properties and microstructure serves to establish a target range of microstructural states that will perform. In order to attain a target microstructure it is necessary to understand what microstructures are, and how they evolve in processing. This presentation focuses upon the set of tools that must be combined to achieve this control:1. Geometry 2 Thermodynamics 3. Kinematics 4. Kinetics. The content of these tools is reviewed briefly and their uses illustrated in developing an understanding of how microstructures evolve. In this development an attempt is made to carry the description of each microstructural process as far as possible without making simplifying assumptions. The study of microstructures with this rigorous point of view was termed by F.N. Rhines, "microstructology".
