“…High entropy alloys (HEAs) are novel and specially designed alloys that have multiple principal elements (5 or more elements) in varying proportions (usually between 5% and 35%) to attain high configurational entropy with inhibition of the formation of intermetallic compounds [133]. The elements of HEAs can either be in equimolar or close to equimolar ratios [134,135]. HEAs are referred to as alloys with high entropy, slow diffusion, severe lattice distortion and cocktail effects [136].…”

“…Zhang et al [149] recently reviewed the microstructures and properties of AM-produced high entropy alloys. Some of the common defects that have been found in the additively manufactured high entropy alloys are post-solidification solute partitioning, geometry inconsistency, poor surface quality, thermalstresses, cracks and inherent internal defects [134]. Although defects like cracks and pores were decreased with an increase in the volume energy density during the L-PBF-processing of the AlCoCrFeNi2.1 eutectic HEA [150], there is still a need to examine post-processing strategies for mitigating these defects.…”

The application of Metal Additive Manufacturing (MAM) in the aerospace industry has been gaining attention. The poor surface quality of parts greatly limits the prospects of MAM-produced parts in the aerospace industry as fatigue performance hinges on a good surface finish and homogeneous microstructure. Post-processing treatments are important to improve the surface quality and the overall performance of MAM-produced parts during static and dynamic loadings. This paper provides a review of the current state of post-processing treatment options for MAM-produced parts. The advances in the post-processing treatments of MAM parts to improve fatigue strength, tensile strength, surface integrity and other properties of parts are reviewed. Future research prospects on metal additive manufacturing of aerospace parts are briefly expounded.

“…In all electrodeposition-related synthesis attempts, at most, a few selected compositions were achieved, occasionally with even dissimilar components. A single work set the target of synthesizing a compositional library with a quasi-continuous composition variation in micropillars [42]. However, in latter work, the sample geometry allowed a composition study only, and the deposit properties as a function of the constituent concentrations could not be revealed.…”

Multi-principal element alloys (MPEAs) are at the forefront of materials science due to their large variety of compositions, which can yield unexplored properties. Mapping the structure and properties of a compositional MPEA library in a reasonable time can be performed with the help of gradient samples. This type of specimens has already been produced in both bulk and layer forms. However, combinatorial MPEA coatings have not been synthesized by electroplating, although this method has a great potential to deposit a coating on components with complex shapes. In this study, a combinatorial Co-Fe-Ni-Zn coating with the thickness of 4 μm was synthesized by electrodeposition. The material exhibited a well-defined Zn gradient; therefore, the investigation of the effect of Zn concentration on the microstructure and mechanical properties was feasible without the production of an excessively large number of specimens. The Zn concentration was controlled laterally through mass transfer due to the unique geometry of the substrate, and it covered a concentration range of 18–44 at%. The chemical and phase compositions as well as the morphology of the as-processed samples were investigated in multiple locations using X-ray diffraction and scanning electron microscopy. The mechanical performance was characterized by nanoindentation. It was found that for any composition, the structure is face-centered cubic and the lattice constant scaled with the Zn concentration of the deposit. The hardness and the elastic modulus were consistent with values of about 4.5 and 130 GPa, respectively, in the Zn concentration range of 25–44 at%.
