“…The change in mechanical properties under dynamic alloying [ 35 , 41 , 42 , 43 ] indirectly points to a change in the material’s physical properties, and the peculiarities of the dynamic alloying process in the SDP mode should increase the anisotropy of the material being processed.…”

“…The authors of the publications [ 26 , 27 , 28 , 29 , 30 , 31 , 32 ] studied the effect of dynamic action on several materials, which showed a significant effect of dynamic action on the structure, chemical composition, and properties of the processed materials. The authors of papers [ 33 , 34 , 35 , 36 , 37 ] investigated the effect of high-energy exposure combined with the impact on the target by a stream of high-speed particles.…”

Dynamic Alloying of Steels in the Super-Deep Penetration Mode

et al. 2022

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. As a result of the completion of the growth of reinforcing fibers in the volume of the W6Mo5Cr4V2 high-speed tool steel, the material’s bending strength in 1.2 times is realized. Simultaneously, it provides an increase of wear resistance 1.7–1.8 times.

“…The recent experiments showed that when streams of cosmic dust particles collide with a spacecraft shield, it causes an occurrence of plasma, which in turn leads to the appearance of electromagnetic radiation capable of disabling nearby electrical equipment and superficial mechanical damage [1,6,7]. However, studies of dynamic alloying in the superdeep penetration (SDP) mode [2][3][4][5] also show that the collision of a high-speed cosmic dust streams should lead not only to electromagnetic radiation and superficial mechanical damage but also to penetration of cosmic dust particles into the spacecraft shell. Using dynamic alloying with high-speed streams of powder particles [10] will allow us to evaluate the effects that occur in the structure of material of the spacecraft.…”

The dynamic alloying of aluminum and its alloy with a high-speed stream of silicon carbide (SiC) particles simulates the effect of a stream of cosmic dust on spacecraft materials. The study showed a structure change in the volume of aluminum and its alloy and the formation of new structural elements. The transformation of the structure during dynamic alloying leads to a change of the composition and mechanical properties of the matrix material.
