A Study of Morphology of Titanium Powder Used in Electron Beam Melting

Electron beam melting (EBM) has been recognized as a revolutionary manufacturing process. This layer-by-layer additive manufacturing process has shown great promise for fabrication of biomedical implants and aerospace components. This paper represents an investigation into the particle size distribution, morphology and flow-ability of Ti6Al4V powder used in EBM process. The effect of recycling of the powder on the chemical properties has been investigated. Results show that recycling increases the weight percentage of interstitial elements. The flow-ability and apparent density of the powder were measured before and after recycling process and no change was observed.
