Electron beam melting (EBM) is a powder bed fusion additive manufacturing (AM) technique that
produces three-dimensional (3D) parts by fusing metallic powders with a high-energy electron beam.
Powder has been major issue for the properties of the final parts. Hence, establishing the effect of the
powder characterization is important for producing parts of quality. In this study; Ti-6Al-4V powder
was characterized in terms of the particle size distribution (PSD), apparent density, tap density,
flowability in Hall Funnel flowmeter, X-ray diffraction analysis (XRD), chemical analysis (LECO)
and particle morphology. The specimens were printed by the Arcam EBM A1X machine is a well-
known effective manufacturing process. The microstructural heterogeneity, defect distribution and
mechanical properties were investigated. The samples were prepared for using standard
metallographic methods. Backscattered electron (BSE) imaging were conducted to investigate the
spatial distribution of microstructure features.
