Dislocation–obstacle interactions at the atomic level
DJ Bacon, YN Osetsky, D Rodney - Dislocations in solids, 2009 - Elsevier
Dislocation–obstacle interactions that resist the glide of dislocations in metals, and hence
increase the applied stress necessary for plastic deformation, are treated at the atomic scale …
