Microstructure and Properties of WC Spheres

Abstract

Tungsten carbide (WC) spheres are used as projectiles to study the ballistic performance of armor materials and systems. In order to properly understand and model the interaction between the projectile and the armor, it is necessary to have properties of both. In this study, the physical and mechanical properties of two commercially available WC spheres (nominally 0.25 inch in diameter) used in some ballistic impact studies were determined. One WC sphere had higher density, elastic properties, and hardness but lower strength and fracture toughness compared to the other sphere, indicating a significant difference in the binder content between the two materials.
