| Annotation: | The main aim of the proposed project is to develop next generation ultra-high temperature ceramics capable of withstanding temperatures up to 3000°C for propulsion systems, rocket engines and other aerospace applications. This will be achieved by the synthesis of diboride ceramics with unique compositionally -complex structures, comprising of at least five metal elements. A systematic study will be conducted to generate new knowledge on the understanding of the effect of various molar ratios of individual metal cations in diboride structures on the stability, synthesis, sintering and mechanical properties of bulk diboride ceramics. The results will significantly contribute to the expansion of the high entropy ceramics concept with equimolar compositions towards the development of compositionally-complex ceramics with non-equimolar compositions. The project also proposes an innovative way of manufacturing ultra-high temperature ceramics, consisting of the development of ceramic composites based on the high-entropy and compositionally-complex diboride matrix, reinforced with the refractory additives. The output of the project will be new fundamental knowledge on the formation of disordered diboride structures, and their effect on mechanical properties of the materials at room, intermediate, and ultra-high temperatures. |
