Meeting 2022 TMS Annual Meeting & Exhibition
Symposium Additive Manufacturing of Refractory Metallic Materials
Presentation Title Laser Assisted Cold Spray Deposition for Niobium and Tantalum Materials
Author(s) Brett Elizabeth Tucker Roper, Luke N Brewer, Paul G Allison, Andy Deal, Tim Eastman
On-Site Speaker (Planned) Brett Elizabeth Tucker Roper
Abstract Scope This presentation will describe the first results on the application of in situ laser heating during the cold spray deposition of niobium and tantalum metal powders. High pressure cold spray is a solid-state deposition process in which powders are accelerated through a converging-diverging de Laval nozzle to supersonic velocities and then plastically deform upon impact with a substrate to create a fully dense deposition. In this research, we employ in situ laser heating to assist with deposition and to modify the deposition microstructure. The microstructure of the deposited materials is being characterized by optical and electron microscopy, with the use of electron backscatter diffraction, in particular. The presentation will describe changes in microstructure as a function of laser heating. This work was funded by the Department of Energy’s Kansas City National Security Campus which is operated and managed by Honeywell Federal Manufacturing Technologies, LLC under contract number DE-NA0002839.
