000015436 520__ $$2eng$$aWe aim to investigate the interaction between an edge dislocation and a self-interstitial-atom cluster in body-centered-cubic Fe. In our simulations, dislocation climb mechanism is introduced into the deformation process at low strain rates, and a newly discovered defect attached to the dislocation line pins down the dislocation incompletely at high strain rates. The difference on thermally activated mechanisms during the dynamic response of plastic deformation induces the variation of critical resolved shear stress, which reflects the lattice resistance of dislocation gliding. In this study we see the coupling of strain rate and thermal activation governs nonequilibrium reaction mechanisms in the defect evolutions.
