Summary

The use of structural ceramics for high-temperature application requires the development of assessment techniques for materials selection. Such materials will be required to sustain loads as high as 300 MPA for extended periods at temperatures as high as 1500°C. Creep and creep rupture will be the primary modes of failure. Therefore, we discuss the development of fracture maps for characterizing creep and creep rupture behavior at high temperatures. Maps are presented for ceramics currently being considered for turbine or heat exchanger applications. Methods of obtaining fracture maps in an efficient manner are described. Finally, the attributes of current high-temperature ceramics are compared.
