“…Agrawal et al effectively printed a new metastable Fe 40 Mn 20 Co 20 Cr 15 Si 5 without any cracks and a small void volume percentage (≈0.1%). [ 108 ] The HEA showed outstanding strength–ductility synergy under tensile loading because of the uniform distribution of the void and the work hardenability of the material. Niu et al evaluated the compressive strength of an equimolar SLM CoCrFeMnNi HEA.…”

“…However, the PBF-LB/M process is characterized by unique thermo-mechanical conditions, like high cooling rates in the range of 10 6 K/s [10] and a cyclic re-heating during melting of consecutive scan tracks and layers. Especially the high cooling rates open up possibilities for developing and processing novel alloy classes, like bulk metallic glasses [11] or compositionally complex alloys or high entropy alloys, respectively [12]. However, the range of possible alloy compositions is vast and the availability of pre-alloyed powder is limited.…”

“…A number of papers have been published on the use of refractory high entropy alloys (see chapter 6). In this case, a BCC structure is always developed [42,[68][69][70] An interesting microstructural analysis of the MA HEAs is also made in the above mentioned study [22]. From this analysis the authors classify this family of alloys in four specific groups: CoCrFeNi, AlxCoCrFeNi, CoCrFeMnNi and Ti25Zr50Nb0Ta5.…”

“…But considering this review of additive manufacturing, many studies exist with relevant results on tensile features. Most of these investigations have obtained the data from parts processed by SLM [38,44,45,49,56,[70][71][72][73][74][75], although there are some others that explored the tensile behavior over EBM materials [40,52,75,76] or processed by DMD methods [28][29][30]33,35,37].…”
