Printing Parameter Determination And Characterization Of Additively Manufactured Kovar Steel, Will Macgreggor Davidson
Mechanical Engineering ETDs
Kovar (ASTM F15, UNS K94610) steel has many applications across Sandia National Laboratories but is best known within academia and industry for its glass-to-metal and glass-to-ceramic hermetic sealing capabilities. Successful printing parameters for a Renishaw AM400 to additively manufacture artifacts from Kovar steel powder have been determined. The printed test artifacts have been studied for ultimate tensile strength, density, surface roughness, hardness, bulk composition, and impact toughness. Longer throughput measurements such as porosity, coefficient of thermal expansion, and grain structure studies have been established for future delivery to the research team. Yet another delivery from this thesis research is a …
