3D Dislocation dynamics modelling of interactions between prismatic loops and mobile dislocations in pure iron

Abstract:

3D Dislocation dynamics simulations have been carried out to model the interaction between prismatic loops and dislocations in pure iron subject to uniaxial loading conditions. The primary goal was to understand the mechanism of interaction of an a/2 <1 1 1> interstitial loop and a mobile dislocation. The secondary goal was to investigate the dependence of the critical stress needed for dislocations to overcome the obstacles as a function of size of loops and their orientation with resp...
