Abstract
In this work, the features of plastic deformation of titanium and aluminum plates under high-speed impact conditions were studied. The structure and phase composition of the explosively welded bimetal were analyzed using both scanning and transmission electron microscopy. The deformation and heating of titanium and aluminum under high-velocity impact were simulated using the smoothed particle hydrodynamics method. The features of shockwave and deformation-thermal processes during the collision of plates were described. The phase composition of the weld and heat-affected zone have been studied. The contribution of the welded plates to the jet formation is estimated.
