Interlayer Oxidation Effects on Mechanical Properties of 316 Stainless Steel Produced by Laser Direct Energy Deposition 

Oxide dispersion strengthened (ODS) alloys are distinguished by the homogeneous distribution of nanoscale oxide particles within a metallic matrix. These materials have been developed to meet the demanding requirements of advanced technological applications, such as gas turbines, which necessitate enhanced mechanical strength and creep resistance at elevated temperatures, as well as environments exposed to high-energy neutron irradiation, as encountered in modern nuclear reactors. Additive manufacturing (AM) presents a promising pathway to streamline and potentially shorten the conventional sintering-based processing route for ODS materials, while also enabling the direct fabrication of geometrically complex components in a more sustainable and efficient manner. In this study we are focussing on adjusting the print parameters and environment during manufacturing and studying the oxide layer generated in the material and then test the various materials in creep and in burner rig environment to see the performance of the same and compare it to conventional material and additively manufactured metal without oxide to see the improvement in performance. The study will include optimizing the oxide layer and comparison of the mechanical properties of materials both in room temperature and at working temperature (in furnace and in a burner rig)  with varied amount of oxide later on the material.

Presenting Author Biography: Dr. Mani, obtained his Bachelor of Engineering (B.Eng. 2009) degree in Mechanical Engineering from SASTRA University [India] and later completed his Master of Science (M.S. 2011) and Doctor of Philosophy (Ph.D. 2014) degrees in Mechanical Engineering from The University of Akron [Akron, Ohio, USA]. Dr Mani is presently Associate professor of Engineering Practice in the Department of Mechanical Engineering at The University of Akron [Ohio, USA]. He is the author of over fifty plus [50+] technical publications in archival journals, proceedings of national and international conferences. His research interests, involvement and expertise span the domain of mechanical behavior, to include failure and fracture analysis, of materials spanning the broad spectrum of: (i) metals, (ii) their alloy counterparts, (iii) metal-matrix composites, (iv) ceramics, (v) ceramic matrix composites, and (vi) emerging materials for use in high temperature applications. His current research interest and involvement is the use of innovative testing techniques to understand the mechanical behavior of novel materials, spanning both engineering (metals) and engineered (composites), for use in both performance-critical and non-performance-critical applications in the industries spanning space and aerospace.
