Description
Summary:The paper presents the results of a comparative study of the structure, mechanical and magnetic properties of bimetallic materials obtained by explosion welding technology. The main layer of the studied bimetals is made of high-strength hull steel, and cladding – was performed by two corrosion-resistant steels with different degrees of austenite stability. According to the results of the shear test, it has been shown that explosion welding provides a solid one-piece connection with high values of the bond strength of the layers. Installed informative magnetic parameters could be used to develop non-destructive methods for assessing the changes occurring in the structure and phase composition of one of the bimetal layers under the action of plastic deformation. The work was partially supported by the RFBR, grant No 16-38-60027. The researchers used the equipment the “Plastometriya” collective use center.
