Preparation of a Light-Weight MgCaAlLiCu High-Entropy Alloy

Article Preview

Abstract:

In this paper, a light-weight equimolar MgCaAlLiCu high entropy alloy (HEA) is reported. The microstructure of the alloy cast in copper mould was composed mainly of a solid solution phase with tetragonal symmetry structure, presenting the high-entropy alloy nature. The alloy exhibited high fracture strength of 910 MPa during the room-temperature compression process. Based on thermodynamic calculation, the underlying reason for the formation of the solid solution in the MgCaAlLiCu alloy is given.
