摘要

This work prepared a new lightweight multiphase Al2.7TiVCrCu high-entropy alloy (4.97 g/cm3) by a multi-stage melting process. The microstructure of soft and hard phases formed after homogenization and annealing effectively improved the compressive properties. The compressive strength reached 1805 MPa and the strain at break reached 32%.
