Physical Mesomechanics Vol. 25, № 1. P. 26-32Abstract: In the present paper, we study strength anisotropy of VT6 titanium alloy additively manufactured by laser metal deposition. The Hugoniot elastic limit and spall strength of the alloy are measured depending on the direction of deposition, the ratio of primary and secondary powders, and preliminary heat treatment. The measurements are performed by recording and analyzing full wave profiles under shock compression at the amplitude 10 GPa. The additively manufactured titanium alloy demonstrates strength isotropy, and its strength characteristics are slightly higher than those of conventionally manufactured industrial specimens. The concentration of secondary powder during additive manufacturing also exerts no effect on strength properties of the alloy, both under static and dynamic loads.
