“…PDMS launch pads were in use shortly after for much more precise single particle launch and increased velocity control. Aiming for higher velocities, Veysset et al more recently designed a launch pad eliminating the elastomeric layer, which partially dissipates the plasma-induced acceleration forces (113). Higher velocities could be obtained for heat-resistant ceramic particles via direct plasma drag acceleration.…”

High-velocity microparticle impacts are relevant to many fields from space exploration to additive manufacturing and can be used to help understand the physical and chemical behaviors of materials under extreme dynamic conditions. Recent advances in experimental techniques for single microparticle impacts have allowed fundamental investigations of dynamical responses of wide-ranging samples including soft materials, nano-composites, and metals, under strain rates up to 10 8 s -1 . Here we review experimental methods for high-velocity impacts spanning 15 orders of magnitude in projectile mass and compare method performances. Next, we present a review of recent studies using the laser-induced particle impact test technique comprising target, projectile, and synergistic target-particle impact response. We conclude by presenting the future perspectives in the field of high-velocity impact. FIG. 1. Impact testing techniques and applications, along with lines of constant characteristic strain rates. All-capital labels are associated with shaded regions of the same color.

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.
