AB  - The well-known indentation size effect (ISE) is reviewed with special emphasis on the effect of grain size in the polycrystalline matrix. It is demonstrated that there is a close connection between the Hall-Petch relationship and the characteristics of the ISE phenomenon such that the ISE phenomenon may disappear in an ultrafine-grained (UFG) matrix. This finding is significant in any attempts to interpret nanoindentation measurements performed on UFG materials.
