Research progress on high entropy alloys by selective laser melting

In recent years, high entropy alloys have attracted great attention in various fields due to their multiple principal components, unique structures, and many excellent properties. This new type of alloy based on “configurational entropy” design is expected to break the performance limit of traditional alloys and has become one of the new hotspots and directions in the development of materials science. The traditional arc melting technology has limited the production and industrial application of hig entropy alloy complex structural parts. The emerging additive manufacturing technology has become one of the most promising manufacturing methods in the preparation of complex metal components. It summarized the latest advances in selective laser melting of high entropy alloys, including processes, optimization, and applications. And the industrial application of high entropy alloys in the future was prospected.
