The necessity to combine analyses of the intragranular plasticity with the effect of the locking of dislocations close to the grain boundaries is emphasized and shown to describe reasonably well the Hall-Petch behaviour of polycrystals of grain size larger than a few micrometers. Extrapolation of t

The Hall polynomial g p counts subgroups of type and cotype in a finite Ž . abelian p-group of type . We derive a formula for g p , along the lines of T. Klein's original formula but much simpler, which shows that its expansion in powers of p y 1 has nonnegative coefficients.
An inverse Hall-Petch effect has been observed for nanocrystalline materials by a large number of researchers. This effect implies that nanocrystalline materials get softer as grain size is reduced below a critical value. Postulated explanations for this behavior include dislocation-based models, di
We propose a composite model to explain the phenomena of strength softening with decreasing the grain size, which was reported in some nanocrystalline (nc) materials. We assume that a nc material consists of a grain interior and an amorphous grain-boundary layer. The grain interior deforms elastical
