- Abstract
Microstructure and antiballistic protection characteristics for two types of titanium-based layered materials are studied. Binary layered armour material consisted of Ti-6Al-4V alloy and Ti-6Al-4V-10% vol. TiC metal matrix composite layers are produced using powder metallurgy and subsequent HIP treatment. Ternary Ti-6Al-4V/CP-Ti/Ti-6Al-4V armour plate is made using additive manufacturing technology. Both types of materials demonstrated a significant superiority in ballistic resistance to armor-piercing incendiary cartridges compared to uniform titanium alloys. Material microstructure and hardness, projectile penetration depth and kinetic energy are analysed to understand contribution of each layer in projectile retardation and energy dissipation. Hard front composite layer effectively retards the projectiles than softer and ductile Ti-6Al-4V and CP-Ti layers, while combination of these materials ensures lower penetration depth and absence of armour cracking on high-energy ballistic impact.
