The mechanical behavior of additive manufactured Ti-6Al-4V was investigated. Round bar tensile specimens and Taylor impact cylinders were machined from rods manufactured by direct metal laser sintering with EOSSINT M2 80 machine considering different printing orientations. Tensile tests were performed at strain rate ranging from 5E-4/s to 5000/s. High strain rate tests were performed with direct-tension split Hopkinson bar. Material strength was modelled using the Johnson-Cook model modified to account for stress saturation at large strain. The model was verified predicting the deformation in Taylor anvil impact tests performed at different impact velocities.
