Ceramic materials having melting points higher than 3000° C and suitable for structural
applications at above 2000° C are commonly known as Ultra-High Temperature Ceramics …

Composites are, in general, a rapidly evolving and growing technical field with a very wide
range of applications across the aerospace, defence, energy, medical and transport sectors …

Ultra-high temperature ceramics (UHTCs) have played a significant role in fulfilling demands
for the thermal protection system (TPS) in the aerospace sector, however, a promising …

Some aspects of heat transfer upon the interaction between components with a sharp
leading edge and high-enthalpy high-speed flow of dissociated air have been considered; …

Pure ZrB 2 powder was Flash sintered in an SPS furnace (FSPS). The samples were
densified up to 95.0% in 35 s under an applied pressure of 16 MPa. Compared to …

Conventional gas turbine blades often face corrosion and oxidation at high temperatures.
For resolving these problems, another way in addition to the cooling ducts is selecting …

A dual-scale hybrid HfB 2/Cu-Hf composite with HfB 2 microparticles and Cu 5 Hf
