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), fibre 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 (channelled) - germs of reinforcing fibres arise. At the subsequent heat treatment, there is an intensive diffusion. The growth process of reinforcing fibres shifts to higher temperatures (as compared to the standard mode), leading to an increase in the bending strength of the fibre material up to 13 times for high-speed tool W6Mo5Cr4V2 steel. As a result of the completion of the growth of reinforcing fibres in the volume of the W6Mo5Cr4V2 steel, the material's bending strength in 1.2 times is realised. Simultaneously, it provides an increase of wear resistance 1.7-1.8 times.

“…This physical phenomenon occurs only in a closed system. Unlike classical alloying, SDP introduces alloying elements into an already solid body and to a greater depth than when using surface hardening and ion implantation methods [ 7 , 8 , 9 ].…”

“…Slamming of microcavities under the action of high pressure to a point can lead to energy density ≥10 15 J/m 3 . In this case matrix crystal lattice is destroyed with high speed [7], and the matrix material changes from a solid state to a dense plasma, i.e. a dynamic phase transition is realized.…”
