Development of Tungsten Based Composites
Abstract
The objectives of this program were to develop the test facility for very high strain rate shear testing of composite tungsten materials for use in kinetic energy (KE) penetrators, to test some composites prepared by liquid phase sintering and by the Hot Isostatic Pressing (HIP) process, and to determine whether the test samples exhibit evidence of favorable KE properties. An electromagnetic stress wave generator, with its output augmented with a conical Hopkinson bar, was used to drive a half-inch diameter punch through tungsten composite samples 1/16 inch thick and one-inch diameter. Initial strain rate on impact was up to 2.4 x 107 sec-1, decreasing as the punch was decelerated by the test sample's resistance. Metallographic examinations were made; however, it is too early to report on promising trends.
