Understanding twinning mechanism is crucial to effectively tailor twin-related properties of HCP metals. Here, we reported an uncommon twin phenomenon during rolling of tilted Mg alloy sheets: coexistence of {10−12} extension twin (ET) and {10−11} contraction twin (CT) inside the same grain. 26 such...
