In different stages of the technological process of fabrication of components and sections from laminated composite materials (LCM) produced by explosive welding, it is necessary to use the operations associated with subsequent plastic deformation (straightening, bending, rolling, etc). In addition, the operation of the structural members may be associated with the formation of elastic or plastic deformation in different areas of the structure. Therefore, the consideration of the effect of deformation on the structure and properties of the LCM is an important aspect in the design and calculation of structural components and sections. In this work, investigations were carried out into titanium VT 1-0-steel 12Cr18Ni10Ti bimetal and AMg6AD1-VT1-0 trimetal, used widely as transition elements in the fabrication of important welded structures. The effect of the stress-strain state (SSS) on the nature of hardening of the weld zone of the VT 1-0-12Crl 8Ni l 0Ti welded joint was investigated on specially prepared specimens with a size of 130 x 6 x 8 mm (the thickness of the steel layer 5 mm, titanium 1 mm) subjected to tensile loading and bending.
