Abstract:

A technique for the preparation of polycrystalline forms of copper with grain sizes in excess of 25 mm makes it feasible to prepare targets for ballistic test in which the deformation of the perforation processes occurs within a few crystal grains or even within a single grain. A description of the process of target preparation is presented, some crystallographic aspects of penetration studies are discussed, and data from tests in which missiles impacted against targets at velocities from 0.6 to 3.6 kmsec are presented.
