Abstract
This paper describes the study of the influence of a microstructure characterized by directed or chaotic distribution of nanoinclusions and strain rate on the deformability of nanocomposites. It is revealed that, under identical loading conditions, cracks are formed in nanocomposites whose structural elements are mostly directed in the same way at lower strain rates than in nanocomposites with chaotic distribution of the reinforcer. It is shown that, as the strain rate increases, the influence of the structural order on the limiting deformation reduces due to transition from shear strain to rotational strain. No cracks are formed in the creation of bonds between metals and nanocomposites by explosion welding. The experimental results obtained in the study of transverse bending of two-layer welded beams and the structure in the vicinity of the weld reveal that the obtained metal–nanocomposite bond has a uniform structure retained in deformation, with fracture occurring in the nanocomposite.
