“…With an increase in deformation to 13 %, microhardness increases to 2.51 GPa (by 15 %). In addition, structural elements (grains, subgrains) deform along the direction of loading, the intensity of shears increases in the primary and secondary sliding areas [14]. The fragmentation of the sliding lines due to changes in the shape of structural elements testifies to the non-uniformity of the external stresses along the traces of sliding.…”

The peculiarities of the accumulation of structural and mechanical defects on the surface of the D16chT aluminum alloy under significant plastic strains are analyzed. The peculiarities of the surface strain hardening are found, and the geometrical parameters of the relief formations are described. The relationship between multiple cracking and specimen deformation is established. It is proved that the deformation relief parameters can be used to assess damage of the D16chT alloy under static deformation.

“…Sheet titanium and aluminum alloys, as well as stainless steels, are widely used for the manufacture of modern aviation and rocket structures. During operation, they are subjected to complex types of loading, in particular, cyclic ones [11,12,13,14]. Therefore, the task of extending the fatigue life of such materials is very relevant.…”

It was shown previously that cyclic loading can be used to extend the fatigue life of sheet plastic materials subjected to the preliminary impact-oscillatory loading. This type of loading causes dynamic non-equilibrium processes (DNP) in materials, which lead to the formation of dissipative structures in materials and on their surface. The density of these dissipative structures is less than that of the base metal. In this paper, the results of investigations into the relief and hardness of surface layers modified by impact-oscillatory loading are analyzed on the example of five structural materials. The signs of a regular, orderly system of microextrusions formed on flat surfaces of all materials due to DNP are considered along with the alignment of roughness parameters Rz and Ra of relief profiles. The effect of impact-oscillatory loading is one of the main causes that lead to the extension of the fatigue life of materials.

“…12Cr1MoV heat-resistant steel has been widely used to manufacture the key components such as superheaters and main steam pipesoperated at temperatures below 580℃due to its excellent ductility, process ability and weld ability as well as good properties such as microstructure stability, creep resistance and oxidation resistance when serviced at high temperature [1][2].12Cr1MoV is usually produced by adopting the technology of combination of hot rolling, normalizing and high temperature tempering or the rmomechanical control process [3], and the corresponding microstructures are ferrite + granular bainite or ferrite + dispersed granular carbide [4]. For the ferrite + granular bainite12Cr1MoV steel, it is prone to have low carbon lath bundle bainite, marten site and retained austenite in service.…”

The 12Cr1MoV experimental steel with different microstructures were prepared by controlled rolling-relaxation-online low temperature tempering technology. Effect of microstructures on mechanical properties of experimental steels were studied by metallographic method, tensile test and impact test. The content of lamellar pearlite, the content and distribution of granular carbide are the main factors affecting the mechanical properties of the experimental steels. The strength of the experimental steel increases with the increase of lamellar pearlite content, and the elongation increases with the decrease of ferrite grain size and the increase of granular carbide content. But the impact toughness of the experimental steel decreases with the increase of granular carbide content at the ferrite grain boundary. 1
