Research methods - mathematical and physical modeling, as well as experimental research. A comparative analysis of the springback of parts made of sheet steels by quasi-static and pulsed methods is performed. It is determined that the springback effect during the high-speed pulse electrohydraulic deformation depends essentially on the mechanical characteristics of the steels: with the energy density of plastic deformation increasing from 10 to 70 J/cm3, the springback strength of high-strength steels (BH210, BH240, HSLA350) is increased up to 3 times, and ultrahighstrength (DP780 and DP980) - monotonically decreases by up to 50% compared to static deformation. Springback effect intensity also depends on the deformation and speed strengthening of steels, reducing its value up to 2 times for steel HSLA350, up to 20-50% for two-phase steels DP780 and DP980 and slightly for alloys BH210 and BH240.
