This document provides scanning electron microscopy images and descriptions of the powder morphology for 14 commercially available metal powders, including pure nickel powders from different manufacturers, nickel-chromium alloys, nickel-chromium carbide composites, and tungsten carbide-nickel powders. The powders were produced using various processes like water atomization, gas atomization, sintering and crushing, blending, and chemical cladding.
