Article

Some aspects of obtaining alloys of the tungsten–nickel–iron–cobalt (TNIC) system have been investigated by the method of liquid-phase sintering of powder preparations, including those containing nano-size tungsten powders. By varying the initial porosity of the powder preparations, samples of highly porous composites have been obtained. A calculational-experimental method was used to investigate the penetrating power of cylindrical impactors made from TNIC alloys on steel plates. An increase in penetration depth with growth of porosity of the sample has been established in the considered range of impact speeds.
