It is well known that rapid solidification processes can induce an ultrafine grain (UFG) microstructure. Hence, the question bears asking, how much similarity do additively manufactured (AM) alloys, which undergo rapid solidification processing, have with UFG materials? The microstructure of SLM processed 316L will be presented as an example of the type of ultrafine cellular-dendritic microstructure that can develop during the AM processing of many alloys. Similarities and distinctions between the dislocation structure and mechanical properties of this material and UFG materials produced by severe plastic deformation (SPD), friction stir processing, ball milling, etc. will be discussed. Of note is the potential for an excellent combination of strength, ductility, and thermal stability.
