FORMATION OF THE MECHANICAL PROPERTIES AND FRACTURE RESISTANCE CHARACTERISTICS OF SANDWICH COMPOSITES BASED ON THE 09G2S STEEL AND THE EP678 HIGH-STRENGTH STEEL OF VARIOUS DISPERSION

The structure, mechanical properties and impact strength of 5-layered composites based on maraging and low-alloy mild steels are investigated. The effect of subsequent heat treatment on the microstructure and mechanical properties of layered composites is studied. The contribution of the presence of the initial ultrafine-grained microstructure of maraging steel to the formation of the mechanical properties of explosion-welded and thermally strengthened layered composites is evaluated.
