Mechanical Property Comparison of the Soviet BS-41 and the US M993 Armor-Penetrating Cores

Abstract

A comparison of the Soviet Union's BS-41 and US M993 armor-penetrating cores is made. The BS-41 core is composed of coarse-grained tungsten carbide (WC) cemented in nickel, while the M993 core is a fine-grained WC cemented in cobalt. The M993 core was determined to have superior hardness and indentation toughness. The superior properties of the M993 core are attributed to its finer grain size and more uniformly dispersed binder phase.
