Figure 1. (A) Schematic of the powder-bed arc additive manufacturing (PAAM) system applied for producing high-entropy alloys (HEAs); (B) Schematic showing the dimensions of produced thin-wall HEA materials and the sampling locations for various characterization, together with a cross-sectional macrograph showing the areas for metallographic observations. Note that no macro-cracking or porosity was visible on the cross-section. OM: Optical microscope; EBSD: electron backscatter diffraction; TEM: transmission electron microscopy; XRD: X-ray diffraction.
