Аннотация
A dislocation pile-up analysis of the Hall-Petch constant kε for the tensile deformation of polycrystalline lead over a wide range of temperature T and at two strain rates has been made. The predicted and experimental Hall-Petch dependencies kε2 = f (T) are in good agreement. Lower than predicted kε values at very low temperatures are attributed to the high curvature of grain boundaries which experience high localized plasticity and consequent shear banding.
