"Friction Welding for Corrosion Resistant Cladding Applications"
Nathan’s research centers on quantifying and understanding the fundamental variables of the friction welding process—the temperature, stress, strain, and strain rate— that govern the formation of a bond between stainless steel cladding and the base metal, the microstructure evolution at the interface, and the final mechanical properties and corrosion resistance of the clad component. The project will demonstrate the feasibility of using the solid state rotary friction welding technique to apply CR cladding to low alloy steels with improved mechanical properties and corrosion-resistance in comparison to the conventional fusion cladding process, and use this principle to develop a new energy and cost efficient process, “rotational insertion friction welding” to apply CR metal internally to a billet. The friction welding of CR metal to the inner diameter of a billet is intended for proof-of-concept for future industrial pipe extrusion applications.
Doctor of Philosophy in Metallurgical Engineering
Estimated Graduation Date:
After completing his metallurgical engineering BS at the Univ. of MO-Rolla, Nathan worked for Honeywell in Kansas City, MO for about ten years, focusing on forging and forming of stainless steels and other metals for aerospace and defense applications. Honeywell funded his master's degree with CSM and his thesis work, "Comparison of Warm Forging Processes for 304L Stainless Steel". Currently, Nathan is a full-time PhD student at CSM, sponsored by AWS (American Welding Society) to compare friction and fusion welding microstructures and mechanical properties for corrosion resistant cladding applications for the petroleum and chemical industries.
