Microstructure Formation and Evolution in Composites during Liquid-Phase Sintering

  • Theory and Technology of Sintering, Thermal and Thermochemical Treatment
  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

The paper presents a brief literature review on microstructure development in composites during liquid-phase sintering. Two mechanisms of microstructure coarsening in liquid-phase sintered systems are considered: dissolution–reprecipitation and coalescence. The data are systematized in the context of the Lifshitz–Slyozov–Wagner theory and the theory of coalescence at the final stages of liquid-phase sintering. The effect of various physicochemical factors, such as temperature, volume fraction, and time on microstructure development is explained in terms of quasichemical kinetics.
