Reversing Hall-Petch Supplementary Data

This dataset demonstrates the compelling story that the same GB functions as a strong obstacle to GB transmission giving rise to HP behavior but then also provides the genesis for IHP behavior through the formation of glissile GBDs that cause GB migration (non-HP deformation) at much lower stresses in the single dislocation regime. Further, this research offers strong evidence that the dislocation pile-up model, which naturally gives rise to HP physics, is also able to provide a simple explanation for IHP behavior by transitioning in a natural manner from GB transmission to GB sliding and migration.
