Rounded, spherical powder particles for 17-4SS virgin powder. This image shows accretionary coatings affecting powder roundness, pocks (golfball texture), and nubs. A smooth surface is seen in the centered-accretionary particle, while the individual material phases are seen clearly in the left-most particles as orange-peel like structure. The small white line in the figure is 10 μm long (“10 μm” is printed to the right of the white bar).
