- Abstract:
-
Owing to their very high strength, nanocrystalline metals have been extensively studied over the recent years. The direct Hall-Petch law, empirically proportioning the material strength to the inverse square root of its grain size has been shown to break down below a grain size of the order of tenths of nanometers. This phenomenon has been widely rationalized as a gradual switch from intragrain mediated deformation mechanisms to grain boundary mediated deformation mechanisms. This transition ...
