Influence of stacking fault energy on deformation mechanism and dislocation storage …
Partial dislocation emission from grain boundaries in metals with medium-to-high stacking fault energies is observed primarily in the grain size range of a few tens of nanometers. Here we report that a reduction in the stacking fault energy permits the emission of partial dislocations from grain boundaries in ultrafine-grained materials with grain sizes …

During plastic deformation, energy is expended as the integral of the product of stress, σ, and the increment of strain, dε. Most of this work (≈ 99%) is released immediately as heat. However, the remaining energy remains stored in the material. This stored energy is found as dislocations at a density, ρ (mm −2 ).
