Silicon Nitride Microstructure Evaluation Using 3D EBSD Reconstruction
Original language description
The microstructure of ceramic based on the silicon nitride is usually consisting of mixed uniaxial and elongated beta grains. The numerical modelling of material behaviour (i.e. elastic constant calculation, stress concentration, crack initiation and propagation, damage evolution etc.) on the microstructural (grain) level is possible only when detailed and realistic description of the microstructure is available. The classical materialography provides good information about grain structure for materialshaving mostly uniaxial grains where statistical approaches are available. The two dimensional EBSD mapping provides additionally grains orientation and texture information. The complex silicon nitride microstructure can be fully described only by the realistic 3D model. The presented work is concentrated on the preparation of such 3D EBSD model of silicon nitride structural ceramic. There arise a number of obstacles which have to be overcome during individual reconstruction steps. This
