| Abstract Scope |
Ti-6Al-4V (Ti64) samples obtained by electron beam melting (EBM) are studied to analyze as-built and polished surfaces, characterize internal microstructures, and predict the monotonic behavior with an internal state variable model. We investigate the surface roughness, morphology, topography, and chemical and phase composition. We first examine the Ti64 powder morphology pre-sintering to characterize average particle size and unique microstructures. Then the as-built EBM surface is inspected following the standard build procedure but without any machining or mechanical processing of the surface. Note that the ARCAM EBM machine naturally anneals the specimen at about 800°C during the build process. Next some specimens are machined and polished, and the resulting surface is studied in comparison to the as-built surface. The surfaces are characterized using confocal optical microscopy (including laser topography), scanning electron microscopy, electron dispersive spectroscopy (to verify chemical composition), and contact profilometry for standard measures of surface roughness. |
