| Abstract Scope |
Electron beam additive manufacturing (EBAM) can produce near-net shape part preforms by adding material in a layer-by-layer deposition process. In order to produce each layer, a wire feedstock is deposited onto a baseplate via melting with an electron beam. This process, as typical to electron beam welding, is conducted in a vacuum chamber. In order to build optimal parts out of Ti-6Al-4V the build parameters required optimization through an iterative process. These processing parameters were then used to build a right circular cylinder test part from Ti-6Al-4V wire that had samples removed from it for characterization of the material microstructure, chemistry, and mechanical properties of the built material. Consideration for post-build heat treatment impact on material properties and performance will also be discussed. The test results demonstrated that the build parameters optimized for Ti-6Al-4V are producing high quality material with a typically large, columnar grain solidification structure and mechanical behavior similar to that of traditionally processed material. |
