Outline of Final Research Achievements

Through a combined study of in-situ TEM nanoindentation, atomic-scale STEM observation and theoretical calculations, we studied the deformation dynamics and atomic structure of ceramic materials. The deformation microstructure of 4H-SiC was investigated by in-situ TEM observation. Deformation-induced phase transformation was observed by HRTEM. By using electron irradiation induced phase transformations, nanopillars were induced into SrNbOx matrix.
