The dynamic effects observed in collisions represent a specific area of high-energy interaction located at the boundary of mechanics, hydrodynamics, shock wave physics, and alternating high-pressure regions.
The paper shows that in the volume of a solid metal body, as a result of dynamic alloying by a high-speed stream of powder particles in the super-deep penetration mode SDP , fiber structures of altering material arise, forming the framework of the composite material. The stream of powder particles in the metal obstacle following the path of least resistance and the impact of shock waves on particles results in a volumetric framework from the products of interaction between the injected and matrix materials.
When using SDP, defective structural elements channeled —germs of reinforcing fibers arise. At the subsequent heat treatment, there is an intensive diffusion. The growth process of reinforcing fibers shifts to higher temperatures as compared to the standard mode , leading to an increase in the bending strength of the fiber material up to 13 times for W6Mo5Cr4V2 high-speed tool steel.
Simultaneously, it provides an increase of wear resistance 1.

The development of modern engineering and technology in new materials creation, environmental protection, and power engineering is inseparably connected with the solution of a whole set of the most important fundamental problems.
One of these tasks is the creation of efficient approaches to creating new composite materials with a high level of performance properties, reduction of mining, decrease in the need for non-renewable critical raw materials, lowering the energy intensity of production. Resource demands will continue to increase due to global population growth, industrialization, increasing demand from developing countries, and the transition to climate neutrality using metals, minerals, and biotic materials in low-emission technologies and products [ 1 ].
