Electron beam wire feed can be used to build up structures rapidly, compared to power bed fusion methods. A circular thick plate structure was fabricated from Inconel 718, then specimens were cut at different orientations with respect to the build direction. Tensile properties varied significantly depending on the location and orientation of the specimens removed from the plate. EBSD was used to provide texture measurements of the plate material in each location. EBSD was also used to estimate local residual stresses and void content, based on novel methods of post-processing of scan data, for each location where specimens were extracted. Microstructure/property relationships will be discussed with respect to specimen orientation.
