Outline of Final Research Achievements

Sintering is a complicated phenomenon of a huge number of interacting particles. Two methods were used to study the relationship between the complicated microstructure evolution during sintering and its dynamics. One method was the synchrotron X-ray microtomography, which was applied to study the anisotropy in the sintering stress during the viscous sintering of glass particles. The other method was FIB nanotomography which was used to study the sintering of sub micron size Au particles. Furthermore, as an example of microstructure control through sintering, the relation between the sintering of silicon nitride and the high temperature deformation was investigated.
