A heterostructuring strategy is an effective approach for abiding problems referred to as the strength-ductility trade-off. However, tailoring the heterostructure is an arduous problem. This work synthesized hierarchically heterogeneity by combining

The formation of brittle intermetallic compounds and the poor solubility of other metallic elements in Al alloys render the design of high- and medium-entropy Al alloys (HEAls and MEAls, respectively) challenging. Herein, new AlVCr MEAls were develop
