Abstract Scope |
Plate-impact experiments have been performed at the ID-19 beamline of the ESRF on porous plates printed using SLM technique out of AlSi10Mg and Ti6Al4V. The samples contain a large population of voids with different sizes varying from 5 to 120 μm. The tests have been conducted with a single-stage gas gun at different impact velocities ranging from 150 to 650 m/s. The targets have been analysed by X-ray tomography before and after testing, to obtain a 3D reconstruction of the porous microstructure of the samples. In-situ radiography has allowed to obtain time-resolved images of the shape and size evolution of voids. The tests have been monitored with a PDV system which was synchronized with the radiography images to correlate the velocity of the free surface of the target with the initial collapse of the pores and the later spall fracture. |
