“…Therefore, to fabricate MPEAs with desired microstructures and properties, it is essential to establish the processing-microstructure-property relationships for PBF of MPEAs. As such, great efforts in the past few years have been made to uncover the optimized PBF processing parameters for fabricating MPEAs [56][57][58][59]. Several process optimization criteria have also been developed based on different mechanisms, including the well-known volume energy density (VED) criterion:…”

Multi-principal element alloys (MPEAs) have attracted rapidly growing attention from both research institutions and industry due to their unique microstructures and outstanding physical and chemical properties. However, the fabrication of MPEAs with desired microstructures and properties using conventional manufacturing techniques (e.g., casting) is still challenging. With the recent emergence of additive manufacturing (AM) techniques, the fabrication of MPEAs with locally tailorable microstructures and excellent mechanical properties has become possible. Therefore, it is of paramount importance to understand the key aspects of the AM processes that influence the microstructural features of AM fabricated MPEAs including porosity, anisotropy, and heterogeneity, as well as the corresponding impact on the properties. As such, this review will first present the state-of-the-art in existing AM techniques to process MPEAs. This is followed by a discussion of the microstructural features, mechanisms of microstructural evolution, and the mechanical properties of the AM fabricated MPEAs. Finally, the current challenges and future research directions are summarized with the aim to promote the further development and implementation of AM for processing MPEAs for future industrial applications.

“…[79][80][81] For example, HEA is a large category of AM-specific materials, showing outstanding mechanical performance with intricate deformation mechanisms (among others), but has limited applications due to poor machinability. [82] The uniqueness of AM makes manufacturing of HEAs feasible with reduced machining and postprocessing. This recent introduction of AM-enabled HEA applications and the lack of extensive prior studies in HEA drives attention to the use of data-driven thermodynamic tools like high-throughput CALPHAD to study the composi-tionÀstructure mapping.…”

The latest industrial revolution, Industry 4.0, is driven by the emergence of digital manufacturing and, most notably, additive manufacturing (AM) technologies. The simultaneous material and structure forming in AM broadens the material and structural design space. This expanded design space holds a great potential in creating improved engineering materials and products that attract growing interests from both academia and industry. A major aspect of this growing interest is reflected in the increased adaptation of data‐driven tools that accelerate the exploration of the vast design space in AM. Herein, the integration of data‐driven tools in various aspects of AM is reviewed, from materials design in AM (i.e., homogeneous and composite material design) to structure design for AM (i.e., topology optimization). The optimization of AM tool path using machine learning for producing best‐quality AM products with optimal material and structure is also discussed. Finally, the perspectives on the future development of holistically integrated frameworks of AM and data‐driven methods are provided.

“…Shortly after their detailed description by Yeh et al [2] and Cantor et al [3] in the early 2000s, the interest of emerging additive manufacturing technologies for these alloy systems also started. In 2018, the state of research achieved so far was summarized by Chen et al [4], others in 2017 [5], and in 2020 [6]. The work done so far shows the possible outstanding properties of this alloy group.…”

The field of complex concentrated alloys offers a very large number of variations in alloy composition. The achievable range of properties varies greatly within these variants. The experimental determination of the properties is in many cases laborious. In this work, the possibility of using metal-cored wires to produce sufficient large samples for the determination of the properties using arc-based additive manufacturing or in detail wire and arc additive manufacturing (WAAM) is to be demonstrated by giving an example. In the example, a cored wire is used for the production of a CoCrFeNiMo alloy. In addition to the process parameters used for the additive manufacturing, the mechanical properties of the alloy produced in this way are presented and related to the properties of a cast sample with a similar chemical composition. The characterization of the resulting microstructure and wear resistance will complete this work. It will be shown that it is possible to create additively manufactured structures for a microstructure and a property determination by using metal-cored filler wires in arc-based additive manufacturing. In this case, the additively manufactured structure shows an FCC two-phased microstructure, a yield strength of 534 MPa, and a decent wear resistance.
