In this paper, the 7.62 × 51mm FFV round consisting of a tungsten carbide core (Hv 1200) and copper gilding jacket was fired at silicon nitride, titanium diboride and boron carbide ceramics; the results were compared with associated work on silicon carbide. In each case, the ballistic performance of the ceramic was assessed by measuring the DoP into an a aluminium alloy witness block. The performance was then compared to micro-hardness values for each ceramic. Of particular interest is the measure of each ceramic's ability to damage and fracture the tungsten carbide core of the FFV round. This paper will be of interest to armour system designers and manufacturers.
