Case Study: Building an Ultra-High-Temperature Mechanical Testing System
De Guire, Eileen
Ultra-high-temperature ceramics (UHTC's), such as refractory metal borides and carbides, are candidate materials for use in extreme environments associated with hypersonic flight, scram jet engines, rocket propulsion, and atmospheric re-entry. For example, zirconium diboride, and hafnium diboride-based ceramics are candidates for the sharp wing leading edges of future hypersonic aerospace vehicles where temperatures in excess of 2,000 degrees Celsius are predicted. The ability to test these materials near their expected service temperatures is an important step in their continued development. However, the upper test temperature for most commercial testing systems is 1,500 degrees Celsius As a result, little is known about the mechanical behavior of UHTC's at temperatures relevent to the proposed applications.
