Abstract:
The ballistic resistance of a combined cermet material based on a high-hardness ceramic bound with an intermetallide on a high-strength metal substrate, (TiB$_{2}$+NiTi)+Ti, is compared with that of plates of steel, VT1-0 titanium alloy, and Al$_2$O$_3$ corundum ceramics upon an impact with a steel spherical impactor in the region of velocities of about 2500 m/s. Experimental studies of protective barriers upon a high-speed impact were conducted using an experimental high-speed ballistic test bench. Mathematical modeling is based on a model of porous elastoplastic medium with allowance for various mechanisms of material destruction, which was modified for media with a complex composition. It is shown that, in the considered range of impact velocities, during penetration of barriers, the (TiB$_{2}$+NiTi)+Ti material, despite its low surface density, exerts a greater force on the impactor and exhibits greater penetration resistance than steel, titanium, and ceramics.
