“…Whatever the correction, one sees that the larger loop grows, while the smaller loop shrinks. This result is in agreement with bias calculations on single loops, which show that the bias increases with loop size [28,29,30]. Since vacancies and interstitials are produced at the same rate, the number of interstitials in loops stays constant, providing no defects remain in the matrix.…”

“…Whatever the correction, one sees that the larger loop grows, while the smaller loop shrinks. This result is in agreement with bias calculations on single loops, which show that the bias increases with loop size [28,29,30]. Differences in loop evolution are clearly observed for the various corrections envisaged, although they remain small from an experimental point of view.…”

“…On average, the growth rate increases with the loop radius, although values are very scattered. This result is consistent with experiments and with the bias calculations on isolated loops, which show a strong increase of bias for small radii and a plateau at around 10 nm [66,67]. The large scattering of growth rates points to an additional effect of the surrounding microstructure on the loop behaviour.…”

“…In general, small loops tend to exhibit lower growth rates than large loops, which points to an increase of the elastic bias with size. Numerical evaluations of bias of isolated loops are consistent with these findings [65][66][67].…”

“…The PF method in this work is based on the previous method of Rouchette et al [29][30][31], used to evaluate the sink strengths of dislocation loops interacting elastically with PDs. We use an explicit numerical scheme to solve Eq.…”
