Dependence of spall-strength on the intensity of the energy exchanges between macroscopic and mesoscopic scale levels is experimentally studied for four kinds of steels having different chemical composition and thermal treatments. For all the kinds of steel the spall-strength is shown to be maximum when velocity dispersion at the mesolevel equals velocity loss at the plateau of compressive pulse, which corresponds to equilibrium state of energy exchange between scale levels.
