| Abstract Scope |
An understanding of the flow behavior over a range of experimental conditions is a critical requirement in developing, and ultimately using, crystalline materials in structural applications. This presentation examines the flow mechanisms occurring in metals under high temperature creep conditions and then extends the analysis to the creep of ceramic materials. The grain size is an important parameter in governing the flow behavior and these properties became important over the last thirty years with the development of new processing procedures that permit the fabrication of metals with submicrometer or even nanometer grain sizes. These ultrafine-grained materials have become especially important with the realization that they provide the potential for using superplastic processing for industrial applications at strain rates that are exceptionally rapid by comparison with more conventional superplastic materials. |
