Abstract

To understand the channeling deformation mechanism in irradiation-damaged materials, the interaction processes between dislocations and radiation induced defect clusters was investigated by molecular dynamics simulation. Small interstitial Frank loops can be easily eliminated by dislocation, but larger ones can stay at original sites after intersection. Vacancy Frank loops are weaker obstacle to dislocation compared with the interstitial ones and they cannot be absorbed by dislocation at low temperature.
