Results of a study of the effect of the conditions of heat treatment on the structure and properties of explosion-welded steel–aluminum composite with different diffusion barriers are reported. The creation of diffusion barrier from either nitrated steel layer or chromium sublayer between aluminum and steel was shown to increase the temperature stability of steel–aluminum composite at the expense of deceleration of diffusion processes and shift of the temperature range of the onset of the formation of intermetallics to the high-temperature range.
