Structure and Properties of Explosion-Welded Composites from Steels of Different Kinds

The structure and mechanical properties of composite materials based on alloy and carbon steels after explosion welding and subsequent heat treatment are studied. The range of heat treatment modes providing high mechanical properties and minimum structural heterogeneity on the layer interface are determined experimentally. It is shown that the diffusion zone forming in heating of composites from steels of different kinds has a well-manifested structure and phase and chemical heterogeneity depending on the mode of heat treatment.
