Additive manufacturing is increasingly being implemented to structural metallic components, yet the nature of microstructural defects and their influence on the mechanical properties are still work in progress. The purpose of this study is to compare the computational and experimental microstructure/deformation evolutions of additively fabricated materials. In order to measure the process dependent grain structure characteristics and the resulting mechanical properties, high-energy X-ray diffraction microscopy (HEDM) is performed on Ti6Al4V alloys during in-situ loading. For the computational calculations, to meticulously study the effect of microstructural features, such as the prior-beta grain size, primary-alpha colony size, the size and shape of the primary-alpha grains and the volume fractions on the mechanical properties of 2-phase structures, the Fast Fourier Transform (FFT) based full field technique is used to model the elastic, viscoplastic and elasto-viscoplastic deformation regimes. The results help to link the processing parameters of AM parts and resulting multi-scale mechanical properties.
