dc.description.abstract	Deformation behaviour under dynamic compression of Ti-6Al-4V (ELI) produced through additive manufacturing in two different forms; as-built (AB) and stress relieved (SR), was investigated. Both AB and SR specimens were printed using the DMLS EOSINT M280 system. Compression tests were performed on the specimens at strain rate ranges lying between (300s-1-400s-1) and (600s-1-700s-1) using a Split Hopkinson Pressure Bar. This paper presents Scanning Electron Microscope (SEM) micrographs of the resulting fracture surfaces of the tested specimens, as well as scanned surfaces of through cuts, parallel and perpendicular to the load-direction of specimens that did not fracture, with a focus on the microstructural features peculiar to shear and adiabatic deformation.	en_US
