Experimental research on mechanical performance of the lightweight composite slabs Research Progress on the Lightweight High-Entropy Alloys

The high-entropy alloy, a new multi-principal element alloy, contains light elements to obtain the lightweight high-entropy alloy (HEA) with the outstanding property of low densities. Its high strength and hardness, corrosion resistance, and high-temperature resistance allow it to be broadly applied in aerospace, transportation, etc, which has attracted wide attention and research. Its research status is described and its component design methods are classified in this paper. Meanwhile, this paper summarizes its microscopic phase structure and properties of different kinds, including hardness, strength, corrosion resistance, and high-temperature resistance. Finally, its application prospect and the shortcomings of current research are also summed up.
