Popis: The study concerns a new material with an aluminum nitride matrix and a graphene additive. The material was obtained by the hot-pressing method. The material prepared in this way shows the anisotropy of the microstructure. This study focuses mainly on the microstructure of the material. The research contains the microstructure observation of sintered bodies, examination of the phase composition and identification of phases in the composites using the EDS method. Additional SEM observations of generated material fractures were made. Microstructural images were taken using computer-aided analysis, which gave the following parameters: coefficient of particle orientation, phases content, particle size. Such investigation was fulfilled by ultrasonic measurement of an anisotropy of longitudinal wave velocity, which gave an answer to the graphene orientation in the composites.
