 Zusammenfassung: Molecular dynamics (MD) simulations were performed to quantify the effect of the precipitate shape on the interactions with extension twin boundaries in magnesium alloys. Three precipitate shapes, including plate-, cube- and rod-like, were studied. The simulation results indicate that the blocking effect of plate-like precipitate is weakly affected by the precipitate aspect ratio (plate width/plate thickness; so, cube-like precipitate is at aspect ratio of 1), while the rod-like precipitate has a hardening effect decreasing with the increasing aspect ratio (rod length/rod width). This suggests that the plate-like precipitate has an identical hardening effect as the cube-like precipitate and a higher effect than the rod-like precipitate. © 2019, The Minerals, Metals Materials Society.
