Atomic simulations to evaluate effects of stacking fault energy on interactions between edge dislocation and spherical void in face-centred cubic metals

Molecular dynamics study of interactions between edge dislocation and irradiation-induced defects in Fe–10Ni–20Cr alloy

“…[14,15] Many simulations have been carried to explore the interaction between dislocations and these irradiation-induced defects, especially voids and Frank loops, in pure metals or alloys. [16][17][18][19][20][21][22] As for voids, the effects of stacking fault energy (SFE), void size, and temperature on their reaction with dislocations were studied in Cu, and the jog was found to form after their reaction. [16] It was also found that voids can transfer to SFTs in Fe-10Ni-20Cr alloys after interacting with dislocations at 900 K, which leads to a sharp increase in the value of critical resolved shear stress (CRSS).…”

[17] As for Frank loops, after reacting with dislocations, it was shown that the original unpinning effects occur in Cu, [18] as well as the "superjogs" form after interacting with edge dislocations.…”

Simulation study of helium bubble coalescence in tungsten at various temperatures relevant to fusion conditions

“…Atomistic simulation techniques such as MD and DFT are important complementary tools [17][18][19] extensively applied to study He defect energetics, interactions between He and the defects, He effect on the lattice thermal conductivities, and He bubble evolution near the surface or in a matrix [20][21][22].
