Marksa, Novosibirsk, 630073, Russian Federation 2 Lavrentyev Institute of Hydrodynamics of the Siberian Branch of the RAS, 15 Ac. Lavrentieva ave., Novosibirsk, 630090, Russian Federation Abstract The research of the structure and mechanical properties of multilayered composite material, formed by one step explosive welding of the plates of steel 12Х18Н10Т and steel Н18К9М5Т followed by heat treatment, is conducted. Composite material has a high quality of the joints. Bands of localized plastic deformation are detected in the central layers of the welded pack. Such bands formation is undesirable effect, accompanying explosive welding process. The hardness of austenitic Ni-Cr stainless steel in the welded pack increased twofold in comparison with its initial state. The hardness of maraging steel is up by 17 per cent. Age-hardening of the multilayered composite material leads to the growth of maraging steel layers hardness. The observed increase in the hardness of this steel from 4000 MPa to 7500 MPa is due to the precipitation of hardening fine intermetallic phases (Ni 3 Ti, Fe 2 Mo) during age- hardening. The toughness of the multilayered material after explosive welding and age-hardening is not inferior the steel 12X18H10T toughness. Keywords: maraging steel, explosive welding, multilayered materials, heat treatment.
