Description
Summary:A comprehensive review of Additive Manufacturing (AM) of High Entropy Alloys (HEAs) is presented, exploring the opportunities for producing advanced components with tailored properties through design-based alloys. HEAs have emerged as promising metallic materials with unique properties that cater to the needs of modern industries. The utilization of AM, a 3D printing technology, allows for the creation of intricately designed products with minimized defects by tailoring microstructural features. The combination of HEAs and AM offers exceptional mechanical properties, improved wear resistance, and enhanced corrosion behavior by optimizing process parameters. This article thoroughly reviews recent advancements in fabricating AM-built parts using HEAs, focusing on powder feedstock, microstructural aspects, phase formation, strengthening mechanisms, and resulting mechanical properties. Furthermore, it explores various applications of AM-processed HEAs in industries such as medical, hydrogen storage, aerospace, nuclear, coating, and automotive, providing detailed insights into their usage. The challenges encountered during the AM process are discussed, and future directions for enhancing the quality of customized products are outlined. This review article offers valuable insights into the realm of additive manufacturing AM of HEAs, incorporating recent developments. It catalyzes future research endeavors in this field.
