Abstract

Abstract : In article number 2100059, Junsheng Wang and co‐workers report that the heterophase interfaces in Al‐Li alloys show the generalized stacking fault energy (GSFE) decreasing from the middle of δ'‐Al3 Li/θ'‐Al2 Cu/δ'‐Al3 Li composite structures to the edge, leading to interplanar slip along the [001] direction at relatively low shear stress. This interface‐mediated plasticity within the ultrafine δ'/θ'/δ' composite precipitate is expected to solve the origin of strength‐ductility conflicts in future Al‐Li alloy design.
