Specific Features of Tungsten-Based Composite Materials in High-Velocity Collision
RESUMO
The work discusses some features of the production of alloys based on tungsten−nickel−iron (W + Ni + Fe) by the method of liquid-phase sintering of powdered samples, including samples containing tungsten nano-size powders. Samples of high-porosity composites were produced by varying the original porosity. In some cases, additional fillers with substantially lower mechanical properties were added to the W + Ni + Fe alloys for simulation of pores; as a result, the so-called pseudo-porous alloys were obtained. The capability of penetration of cylindrical rods, made from the developed W + Ni + Fe composite materials, into steel armor plates was analyzed in the range of striking velocities 2000−4000 m/s, inter alia, by the calculation and experimental method. Particular attention was given to strikers from high-porosity and pseudo-porous composites with enhanced penetration capability in the case of high-velocity collision, compared to monolithic analogs.
