| Abstract Scope |
Interest in refractory metals has greatly increased with the development and adoption of additive manufacturing. Recent research efforts have focused on the production of C103 thin wall components via Laser Powder Directed Energy Deposition (LP – DED). However, the design of many components include features which require contours and hatching. The introduction of hatch spacing, hatch distance, as well as differences in contour vs hatch speed and power can often require a new set of parameters. This work focuses on the investigation of parameters for printing bulk features and the mechanical response of these. The team explored combinations of laser power, scanning speed, and mass flow rate to achieve an adequate set of parameters. The effect of dwell times between each layer is discussed. Microstructure, microhardness, and tensile testing of cylindrical specimens are presented in detail. Finally, these results are compared to previous development work done for thin wall features. |
