a Morphology of HEA raw powder. b A schematic of three different kinds of processing routes. c, f Electron backscatter diffraction (EBSD) inverse-pole maps of HIP and CR. i, j EBSD inverse-pole maps of SLM from cross-section vertical and parallel to the build direction. d, g, l A bright-field transmission electron microscopy (TEM) image and the corresponding selected area electron diffraction (SAED) patterns of HIP, CR, and SLM samples. e, h, k X-ray diffraction patterns of HIP, CR, and SLM samples. m Three-dimensional (3D) reconstructions of a typical atom probe tomography (APT) tip showing atomic maps of Fe, Co, Cr, Ni, and N in the SLM sample.
