Triple layer titanium-based plate consisted of Ti–6Al–4V and CP–Ti layers 3D-printed on T110 substrate was tested for antiballistic protection. Microstructure after ballistic testing, hardness and three-point flexure characteristics of the layered material were studied and analysed. Interfaces between layers are important structure features contributing antiballistic protection characteristics. 3D-printed layers demonstrated sufficient bonding without porosity and other defects at interfaces, which resulted in promising antiballistic protection against high-energy B32 projectiles. Difference in microstructure, strength, hardness and ductile properties of individual layers resulted in noticeable variation of mechanical behaviour of layered materials depending on direction of applied force giving potential for further improvement of protecting characteristics.
Key words: titanium alloys, 3D-printing, multilayer materials, microstructure, armour, ballistic resistance, mechanical characteristics.
