Crater Characteristics of 11 Metal Alloys under Hyper-Velocity Impact Including Effects of Projectile Density and Target Temperature

Abstract

An experimental research program was conducted to determine the cratering characteristics resulting from the impact of high velocity projectiles in 11 different metal alloys. Spherical Pyrex, aluminum, steel, nylon, and Inlyte projectiles were accelerated to velocities from 4.88 to 8.35 kilometers per second and impacted against thick flat plate targets at room and elevated temperatures. Targets impacted were aluminum alloys 2024-T6, 7075-T6, and 356-T51, columbium - 1 percent zirconium, tantalum, vanadium, molyhdenum-TZM, A-286, Inconel-718, 316 stainless steel, and L-605. Correlations were determined for the effects of projectile density and target temperature on the cratering characteristics of these materials.
