Ballistic Penetration of Titanium Alloy Ti-6Al-4V

摘要

The US Army Research Laboratory and the German-French Research Institute Saint-Louis have jointly analyzed the ballistic performance of titanium alloys against long rod penetrators of different aspect ratios. This paper presents a comparison of penetration data for the ISL L/D 20 tungsten rod and ARL L/D 10 tungsten/depleted uranium and L/D13 tungsten laboratory rods at impact velocities up to 2000 m/s. The titanium examined was Ti-6Al-4V alloy, manufactured to aerospace specification Mil-T-9046J. The titanium and RHA penetration data are presented by concise two-linear analytic functions that describe the penetration-velocity relationship rather well over the range of impact velocities.
