Atomistic mechanisms of twin-boundary-controlled crack propagation in nanotwinned CoCrFeMnNi high-entropy alloys

Twin boundaries (TBs) are effective microstructural features for tuning the mechanical response of face-centred cubic high-entropy alloys (HEAs), but their role in crack-tip deformation and crack propagation remains insufficiently quantified at the atomic scale. Here, molecular dynamics simulations are used to isolate...
