| Abstract Scope |
Boron carbide (B4C) is one of the most commonly used materials for armor applications due to its low specific density and high hardness. However, the high material cost is preventing the wide use of Boron carbide. Numerous studies have been carried out on the production of B4C-containing composite materials by the addition of different compounds such as SiC and TiC.
In this study, optimum boron carbide - silicon carbide - titanium carbide multi-phase ceramic composite compositions were designed and produced by spark plasma sintering to optimize cost and ballistic properties relationship for armor applications. The addition of SiC did not affect the hardness and toughness, but the addition of TiC resulted in increased toughness in spite of decreased hardness. When SiC and TiC were added together, hardness decreased whereas fracture toughness increased. Additives studied in this study decreased the cost but increased the density of composite ceramic. |
