Helium segregation and transport behavior near ⟨100⟩ and ⟨110⟩ symmetric tilt grain boundaries in tungsten

We report the results of a systematic atomistic modeling study of small helium cluster behavior near tungsten symmetric tilt grain boundaries. This behavior was studied qualitatively by molecular dynamics simulations and quantitatively by molecular statics simulations combined with elastic inclusion...
