| Abstract Scope |
The introduction of inoculants during the process of additive manufacturing just as with casting, has shown to be a viable method of refining the microstructure of additively manufactured parts. Many studies have shown that this process is promising but without necessarily discussing how these inoculants are added and how the addition process affects the microstructure hence the motivation for this research. This research aims to perform a critical comparative analysis of the effect of inoculant addition methods on the microstructure of additively manufactured geometries. Achieving this required using three selected processes: ball milling, electrostatic process, and atomic layer deposition. The material system selected was stainless steel (SS316L) and Inconel 718, inoculants chosen were titanium oxide and alumina. The SEM micrographs have shown remarkable adherence of the inoculants to the metal powder. We anticipate that each inoculant addition process will significantly affect the resulting microstructure after printing using the EOS 280M.
