摘要	The impact of macro- and microdamage behaviors of Ti-6Al-4V alloy has been examined using a two-stage light gas gun. Disks with thicknesses from 2 to 20 mm cut from a forged and annealed Ti-6Al-4V alloy bar with the diameter of 70 mm, and plates cut from a rolled Ti-6Al-4V alloy sheet with a thickness of 1 mm, were employed as single- and multilayer targets, respectively. The impact velocities of the spherical steel, 4.0-mm-diam projectiles, ranged from 1 to 4 km/s. For the impacted targets, the crater shape and dimension, microstructures and microhardness distributions in the vicinity of craters were characterized by complementary techniques such as optical microscopy, scanning electron microscopy, and Vickers microhardness measuring. Based on the experimental results, the penetration resistance of the annealed Ti-6Al-4V alloy and the critical impact velocity to form the debris clouds in the Ti-6Al-4V alloy sheet were obtained.
