摘要: Abstract Molecular dynamics (MD) simulations are performed to investigate the interaction of a migrating grain boundary (GB) with interstitial Frank loops, using set GBs along [100] tilt axis in Cu as model systems. Our results show that is directly related misorientation angle. Specifically, three modes observed function The sink efficiency GB, namely, capability GB absorb increases above trends explained based on differences structural units comprising GB. Additionally, transition angle between different can be altered by varying local structure.
