From my understanding, powders utilized for the selective laser melting (SLM) process are manufactured through an atomization process. My question is, do the powders that develop from this process have a single crystalline or single grain structure? I.e. do the individual powder particles manifest as a single grain structure? Or is each powder particle composed of multiple grains? I realize that this is likely a function of the final particle size, so I'd prefer a response that indicates size ranges and the resulting grain structure. E.g. powders on the nanoscale size develop as blank while powders at the micron scale develop as blank.

Thanks,
