With the use of the procedure of a combined specimen, 
the limiting depths of penetration of powder strikers of silicon carbide 
and copper into 45 steel have been found. The efficiency of retardation 
of the strikers by a block of layered obstacles depending on the foil 
material has been determined. Based on the complex analysis of the 
information obtained, it has been proposed that high-speed jets whose 
forepart consists of the microstriker material and whose main rear 
part consists of the obstacle metal are formed in the process of superdeep 
penetration.
