Dislocation density as a function of compressive strain for equimolar polycrystalline MoTaVW alloy containing 12 grains with 100 million atoms at 300 K. a Strain-induced dislocation density (red solid line) and stress (blue dashed line). b–e Distributions of dislocation in 20 nm thick slices at strains of (b) ϵ = 0%, (c) ϵ = 2.5%, (d) ϵ = 6%, and (e) ϵ = 20%, respectively. Grain boundaries are labeled by numbers for reference. The compressed direction is perpendicular to the plane of view. The 1/2〈111〉 dislocations are depicted in green, while other dislocations are shown in red. Source data are provided as a Source Data file88. The initial and final molecular dynamics configurations are provided in the Supplementary Data90.
