| Annotation: | Thematically, the main objective of the proposed project “CAFIHEC” is focusing on the development – processing, characterization, and testing – of new dual-phase high-entropy ultra-high temperature ceramic-based composites reinforced by carbon fibers with an overall aim to develop extremely hard and significantly improved, damage tolerant composites. This new dual-phase HECs provide an excellent platform for controlling physical, thermal, fracture–mechanical, tribological, oxidation, and other properties of the system via microstructural engineering, e.g., by changing the volume fraction, size, and shape of each phase, in addition to tailoring the interfaces. These characteristics allow the materials to withstand extreme environments for potential applications in leading-edge industries such as hypersonic vehicles, and nuclear reactors. This research follows up on the latest world trends, in which Dr. Naughton-Duszova et al. have been published, as described in the State-of-the-Art in chapter 1.2. Intensive investigations on HE-UHTC\’s in the past five years focused mainly on the modeling, processing, and characterization of their microstructure and mainly the basic mechanical properties such as hardness, modulus, and indentation fracture resistance using indentation methods have been studied. A very promising group of these advanced materials developed as potential systems for ultra-high temperature applications is the so-called dual-phase high-entropy ultra-high temperature ceramics (DPHE-UHTCs). |
