Abstract
The final stage of sintering determines the mechanical characteristics of material. Usually the final stages of sintering are optimized via residual porosity and grain size and shape (that are believed to control mechanical characteristics) with the help of temperature and time of sintering. Elimination of residual porosity at final stage of sintering may be accompanied by excessive grain growth. Grain growth may take place as a result of secondary recrystallisation during solid state sintering. During sintering in the presence of a liquid phase, grain growth may be a result of “dissolution-precipitation” mechanism, as well as a result of direct coalescence owing to migration of solid-solid boundaries. A study of the load dependence of hardness and deviations of values of microhardness from the average value can be an instrument of optimization of the final stages of sintering.
