| Abstract: | Two kinds of titanium alloy materials with high strength and high toughness were selected: metastable state β Type TB17 and high damage tolerance α+β Type TC4 DT.The dynamic mechanical response characteristics of two titanium alloy materials under high strain rate condition were tested and analyzed, and the performance of two titanium alloy semi armor piercing warheads penetrating single steel target was tested by 125 mm gun launcher. The results show that as the shell material of semi armor piercing warhead, titanium alloy with good matching of yield strength and impact toughness should be selected, the plastic deformation ability and impact toughness of titanium alloy should be paid more attention. With the increasing of the penetration angle, the erosion amount of the projectile head and the radial pier thickness are more serious after the penetration into single steel target, which is not conducive to maintain the penetration strength and the charge stability of warhead. |
