Abstract Scope |
As applications require greater strength and temperature resistance, new alloys and geometries must be developed for both traditional machining and for additive manufacturing capabilities. In this work, a binary titanium-niobium alloy was successfully printed via Laser Powder Bed Fusion (L-PBF) to successfully form complex geometries. Using a historically successful parameter design of experiments (DOE) selection procedure, parameters that produce homogenous material that is >99.9% dense were established after a single DOE build. These densities were verified via X-ray Computed Tomography (XCT) to down-select parameters that were used to print complex lattice geometries. These geometries range from hatch generated lattice structures to complex triply periodic minimal surface (TPMS) structures. These TPMS lattices were designed to obtain isotropic permeability to assist with liquid metal dealloying of the structures. |
