Additive Manufacturing of High-Entropy Alloys: Microstructural Metastability and Mechanical Behavior

High-entropy alloys (HEAs) have received considerable interest over the past decade due to their intriguing structural, chemical, and physical properties. Additive manufacturing (AM), also termed three-dimensional (3D) printing, generates parts with complex geometries and internal features layer-upon-layer from a computer-aided design (CAD) 3D file. In recent years, explosive research on AM of HEAs has been inspired. This paper performs a...
