Recrystallization and Sintering in Ceramicse to positions of greater stability. In other words, we include phase changes in the solid state, sintering, grain growth, and precipitation or exsolution phenomena. It is important to remember that metallurgists use the term recrystallization in a much more restricted sense: the nucleation and subs

Role of Grain Boundaries in Sinteringl have an important effect on the rate of sintering. Grain growth during sintering changes the configuration of grain boundaries relative to pores and thus may markedly influence the shrinkage rate; for example, for uniformly distributed pores the shrinkage rate will increase as the grain size decre

Sintering Crystalline Solids. I. Intermediate and Final State Diffusion Modelshe important phases of the course of densification. From this guide, appropriate grain shapes and pore shapes and locations are selected for the formulation of diffusion sintering models. The principle models presented are for bulk diffusion transport with the grain boundaries as vacancy sinks when

Sintering Crystalline Solids. II. Experimental Test of Diffusion Models in Powder Compactswith the one-third power of time. Incorporation of the time dependence of grain size increase into late-stage bulk diffusion sintering models (from Part I ) leads to corrected models by which a semilogarithmic behavior is predicted. The presence of density

Solid-State Sintering: Critical Assessment of Theoretical Concepts and Experimental Methodstitative microscopy) is made. Theoretical concepts for quantifying sintering mechanisms are systematically and critically reviewed. It is concluded that present theoretical approaches do not account for the complex interaction of processes during sintering of powder compacts, and that agreement with
