Annotation
Dissertation work is focused on development of novel oxidation-resistant UHTCs through a systematic experimental based study in which the high-temperature properties (oxidation and ablation resistance, thermal shock resistance etc.) and mechanical behaviour of mono and binary refractory carbides will be studied. Different secondary phase materials with the incorporation of silicon will also be tested in the form of SiC and transitional metal silicides, which are known as protective glassy phase-forming compounds that can further improve the oxidation resistance of newly developed UHTCs.
The accomplishment of the present PhD. thessis will generate fundamental knowledge that is needed for the design of novel more complex multi-principal element ceramics. Filling this lack of knowledge would be of great importance for whole materials science community.
