Mechanisms for 100> interstitial dislocation loops to diffuse in BCC iron

The mobility of dislocation loops in materials is of key importance to understanding their deformation behavior. Here the authors using self-adaptive accelerated molecular dynamics show self-diffusion of interstitial loops in body-centered cubic (BCC) iron by changing its habit plane as also confirm...

Zusammenfassung:The mobility of dislocation loops in materials is of key importance to understanding their deformation behavior. Here the authors using self-adaptive accelerated molecular dynamics show self-diffusion of interstitial loops in body-centered cubic (BCC) iron by changing its habit plane as also confirmed by transmission electron microscopy (TEM) measurements.
