چکیده انگلیسی
This is the first comprehensive review on inherent anisotropic features of transition metal diboride (MB2) and their implementation for tailoring the microstructure and properties of MB2-based Ultra-high temperature Ceramics (UHTCs). The emphasis is on the processing approaches, microstructures, and properties of self-reinforced and/or textured MB2-based composites with elongated MB2 grains. The crystal structure characteristics and grain growth behaviour of MB2 are also critically reviewed. Benefiting from the tailored microstructure, the MB2-based ceramics exhibit some improved properties. Considering the success of Si3N4 ceramics in the field of structural ceramics, it is expected that the potential MB2-based ceramic composites with abundant elongated MB2 grains, textured structures, and controlled grain boundaries would possess improved fracture toughness, thermal shock resistance, and reliable high-temperature properties, which are desired for their practical applications. Accordingly, microstructure designing and tailoring provide an important perspective for the future development of UHTCs.
