Abstract For the new marine Ti6321 titanium alloy, the penetration tests were carried out under vertical and oblique penetration conditions. The ballistic properties of Ti6321 titanium alloy with different structures and the macro and micro damage characteristics of the target were obtained. The influence of the structure on the ballistic performance and failure mechanism of the titanium alloy target plate was analyzed. The results show that Ti6321 titanium alloy exhibits different properties under vertical and oblique penetration conditions. In the vertical penetration test, the absolute penetration depth and the average crater diameter of the equiaxed target plate are smaller than those of the bimodal and Widmanstatten structure, which show a better resistance to vertical penetration. In the oblique penetration, the safety angle of the bimodal structure was smaller and showed better resistance to the oblique penetration.
