Using combined deformation processing, including preliminary mechanical activation followed by consolidation via high-pressure torsion, a multi-layer nanocomposite based on nickel and aluminum is manufactured. The influence of the duration of mechanical activation on its microstructure parameters is investigated by the X-ray diffraction analysis and scanning and transmission electron microscopy. It...
Using the methods of transmission and scanning electron microscopy, the defect substructure of a V–4Ti–4Cr–(C, N, O) alloy dispersion strengthened with nanosized oxicarbonitride particles and the features of its fracture after deformation via active tensile loading at the temperatures 20 and 800°C are investigated. It is shown that the most representative features of deformation at the elevated temperature...
