High-entropy alloy is a new type of alloy, its excellent physical and chemical properties have attracted extensive attention of the researchers. However, the density of traditional HEAs is high, which greatly limits their engineering applications. In order to reduce the density of HEAs, the low-density elements such as Al, Ti, Mg, Li, and C are used to prepare HEAs, then, a series of LHEAs at equal molar or non-equalmolar concentrations is successfully prepared, showing great application potential in the fields of aerospace, energy and transportation. This paper reviews the research progress of LHEAs. The design guidelines and processing techniques of HEAs are analyzed. The phase structures and properties of LHEAs are introduced according to their system characteristics. The future research direction of LHEAs is prospected.
