The complex problem of increasing the penetrating power of strikers based on highly porous tungsten composites is considered by improving their strengthening properties by alloying the hardening components under high-speed collision conditions. Using the method of liquid-phase sintering, we fabricated samples of strikers based on a porous WNiFeCo alloy (tungsten + nickel + iron + cobalt), alloyed with tungsten carbide with cobalt (WCCo8) and titanium-tungsten carbide (TiWC). Dynamic tests of the strikers from the developed alloys were carried out at the collision velocity with a steel barrier of the order of 2800 m/s. The penetration depth of the striker based on a porous WNiFeCo alloy doped with tungsten carbides is 30% higher than the penetration depth of a striker of a monolithic WNiFe-90 alloy (tungsten + nickel + iron with a tungsten content of 90%).

The means of production of nanostructured composite materials by the method of self-propagating high-temperature synthesis (SHS) with the application of pressure to the product of combustion and by the method of intensive plastic three-sided a,b,c deformation are considered. A composite material of combined structure is developed, which is a layer system, one of the layers of which is a product of the exothermic reaction of the Ti-B-Ni system in the form of an interlayer produced by pressing the heated SHS product, and the other layer is inert, the role of which is played by the metal layer. The properties of the developed materials, including the TiB2 + B4C-based ceramic metal, are studied under the conditions of high-speed impact.

The behavior of cermets under shock-wave loading conditions is examined. The materials under study are produced by self-propagating high-temperature synthesis. A mathematical model for calculating the stress-strain state and fracture of the TiB + B4C-based cermet is developed.

The results of experimental and theoretical research of shock-wave and spalling phenomena in ultrafine-grained and coarse-grained (α + β) alloy Ti–6.2% Al–4.0% V (wt %) treated by a nanosecond relativistic high-current electron beam are presented. Data on the dynamics of mass velocity, temperature and shock waves as well as on the interaction of the unloading wave with the rarefaction wave reflected from the back surface have been obtained for an axisymmetric position of the target. It is shown that the strain rate increase from 10−3 to 105 s−1 in the both grain structures does not change the fracture mechanism and the phase composition in the zone of spalling. The obtained theoretical dependence of the spalling layer thickness to the target thickness corresponds to experimental data.
