The contract contract No. FA8655-12-1-3004 between the US Air Force Research Laboratory and the Institute of Science and Technology of Ceramics, National Research Council of Italy (ISTEC-CNR) started in December 2011 with duration of 39 months. Objective of the contract was the investigation of various ultra-high temperature ceramics through transmission electron microscopy. The activity included the production of ceramics and microstructural characterization. Transmission electron microscopy was employed as fundamental technique to disclose the sintering mechanisms, microstructure evolution and toughening phenomena occurring in the materials. For selected materials mechanical properties, like fracture toughness, strength and nanoindentation, were measured and correlated to the microstructural features.
