Applying conventional creep mechanisms to ultrafine-grained materials
Applying conventional creep mechanisms to ultrafine-grained materials
The creep behaviour of polycrystalline materials is now well described
through a series of equations that delineate various mechanisms describing intra- granular and intergranular flow processes. The recent ability to fabricate metals with exceptionally small grain sizes within the submicrometer and nanometer ranges has raised questions concerning the applicability of these flow processes in these new and advanced materials. This report examines this problem by initially reviewing the fundamental mechanisms occurring in high temperature creep and then con- sidering the extension of this approach to materials having ultrafine grain sizes.

Abstract
The creep behaviour of polycrystalline materials is now well described
through a series of equations that delineate various mechanisms describing intra- granular and intergranular flow processes. The recent ability to fabricate metals with exceptionally small grain sizes within the submicrometer and nanometer ranges has raised questions concerning the applicability of these flow processes in these new and advanced materials. This report examines this problem by initially reviewing the fundamental mechanisms occurring in high temperature creep and then con- sidering the extension of this approach to materials having ultrafine grain sizes.
