Stepped kinetics of deformation of alloys by pulsed pressure from an expanding plasma channel has been observed. On the deformation curves there are time intervals during which deformation does not vary, and these intervals shorten closer to the central cross sections of the wave source. This is explained by the shockwave nature of pressure transfer. A connection between the parameters of the discharge circuit and the pulsed pressure at the wave front of the expanding plasma channel is established enabling a quantitative estimate with allowance for the dynamic viscosity of the metal.
