ABSTRACT

High temperatures offer advantages or are required for many applications. Materials for a specific high-temperature application are chosen based on their properties at the application temperature, the environment in which they will function, the time at temperature, and the frequency at which they will cycle between temperatures. In this chapter, rather than focusing on a particular group of materials or a particular temperature range, a brief overview of the various classes of high-temperature materials will be given and then some of the general issues associated with high-temperature applications will be discussed and illustrated with some specific examples.
