摘要

The limitation that the dislocation pileup model holds in the individual grains of nanocrystalline materials is analyzed qualitatively. It is shown that the microstructure of nanocrystalline materials has a decisive effect on the formation of dislocation pileups in the grains. The theoretical results can explain the experimental observations well.
