Ultrahigh-Temperature Ceramics

, 2007
Ultrahigh temperature ceramics (UHTCs) are a class of materials that include the diborides of metals such as hafnium and zirconium. The materials are of interest to NASA for their potential utility as sharp leading edges for hypersonic vehicles.

An Evaluation of Non-contact Temperature Measurements for Oxyacetylene Torch Testing of Ultra-High Temperature Ceramics

, 2011
The feasibility of using noncontact measurement devices in oxy-acetylene torch ablation testing for UHTCs has been investigated. UHTCs are candidate materials for use in hypersonic and atmospheric re-entry vehicles for their oxidation resistance and ...

Robust UHTC for Sharp Leading Edge Applications

, 2003
Ultrahigh temperature ceramics have performed unreliably due to material flaws and attachment design. These deficiencies are brought to the fore by the low fracture toughness and thermal shock resistance of UHTCs.
