About
Todd Palmer is a Professor of Engineering Science and Mechanics and of Materials Science and Engineering at Penn State University, where he also serves as the Director of the Center for Innovative Sintered Products. His research interests encompass high energy density processing and joining of structural and advanced materials, with a focus on additive manufacturing of metals, including laser and electron beam techniques. He investigates process-structure-property relationships in additive manufacturing, as well as the application of these techniques to repair and refurbishment of parts. Palmer's work involves the characterization of phase transformations using synchrotron-based in situ x-ray diffraction techniques, and he is actively involved in the development of diagnostics for electron beam welding. His research lies at the intersection of materials processing, microstructural characterization, and materials performance, emphasizing advanced fabrication technologies such as high energy density welding, additive manufacturing, and particulate materials processing in metallic systems. Palmer has contributed significantly to the field through over 100 publications and holds four patents related to electron beam diagnostics. He collaborates with standards organizations and works closely with industry, government, and academia to advance high energy density beam processing, welding, and additive manufacturing technologies.

articleOpen accessWe report a significant improvement in localized corrosion resistance of Ni-based alloy 625 processed by directed energy deposition (DED) in 7.6 mol/L LiCl at 50 oC. Disparities observed in polarization behavior between DED and wrought alloy 625 are analyzed through compositional and microstructural differences. The exceptional localized corrosion resistance of the DED alloy likely stems from the refinement of secondary phases resultant from the DED process. The prototypical precipitates larger…
