Abstract
A metallographic study was carried out on uranium-based and tungsten-based penetrators which had impacted a semi-infinite soft steel target at normal incidence. The uranium alloys show a great tendency to shear adiabatically at the surface. Martensitic U-2Mo is mechanically highly unstable while U-1Mo-.7Nb-.7Zr, in the lamellar condition shows promise as a potential alternative to W-Ni-Cu at impact velocities above 0.76 mm/s. The uranium alloy must be sufficiently hard, however, to avoid significant mushrooming.
