Exploring the sintering behavior of a complex ceramic powder system using in-situ X-ray nano-tomography

Résumé

As a typical example of constrained sintering, the behavior of a complex ceramic powder system with multi-heterogeneities has been investigated. This powder system comprises inherent imperfections as well as rigid inclusions that act as constraints to densification. The sintering process of the system was monitored by in-situ X-ray nano-tomography at the European Synchrotron Radiation Facility (ESRF). This technique enables three-dimensional (3D) imaging of the microstructure with a voxel size of 25 nm. The images obtained reveal the distribution of imperfections in the powder system, such as particle aggregation and pore segregation in and around them. The subsequent in-situ evaluations show the evolution of the microstructure in the presence of inclusions. The study addresses the questions pertaining to the effect of the added constraints, the consequent crack generation and their implication on the final densification of the material.
