Impact loading curves and fracture energy of the notched 12Cr1MoV ductile steel specimens are analysed. The qualitative description and quantitative parameters are obtained for major stages of ductile and brittle fracture depending on the shape of the notch and the stress stiffness ahead. It was shown that a zone with enhanced plasticity forms in the vicinity of V‐, U‐ and I‐shaped notches at 20 °C testing temperature, giving rise to ductile fracture. The stress stiffness at the notch tip increased with testing temperature reduced to −40 °C. We demonstrated that the size of shear lips on a fracture surface is a quantitative characteristic of fracture. Using this approach, which is close by nature to non‐linear fracture mechanics, together with the quantitative description of fracture surfaces, a physical–mechanical scheme of the specimen fracture was suggested for the case of enhanced and localized (constrained) plasticity near the stress concentrator tip.

“…The comparison of the fracture surfaces was carried out at commensurate (but not always the same) magnifications, taking into account the well-known methodological aspects [27][28][29]. This made it possible to establish the main laws of fracture at the macro-, meso-, and micro-levels [30,31].…”

A simple technological method is proposed and tested experimentally, which allows for the improvement of mechanical properties in sheet two-phase high-strength titanium alloys VT23 and VT23M on the finished product (rolled metal), due to impact-oscillatory loading. Under impact-oscillatory loading and dynamic non-equilibrium processes (DNP) are realized in titanium alloys, leading to the self-organization of the structure. As a result, the mechanical properties of titanium alloys vary significantly with subsequent loading after the realization of DNP. In this study, the test modes are found, which can be used in the production conditions.

“…In recent years the attention of researchers in the field of physical materials science is concentrated on the analysis of nature of metals' and alloys' hardening under the action of the external energy influences and concentrated flows of energy [10][11][12][13][14][15] . The promising field of development is a combination of several methods of modification.…”

The analysis of structure, defect substructure, elemental and phase compounds and friction properties of Al-11wt%Si alloy surface layer of subjected to complex treatment was carried out by methods of scanning and transmission electron microscopy. Complex treatment includes the electroexplosion influence by Al-Y 2 O 3 compound and subsequent electron beam irradiation. The surface layer ≈ 80 μm thick is formed by high-velocity crystallization cells of 0.8-1.3 μm in dimension. Interlayers 50-75 nm thick located along the cells of high-velocity crystallization are enriched by atoms of silicon and yttrium. Complex surface treatment leads to the increase by 18 times in wear resistance and decrease by 1.6 times in the friction factor of the modified layer.
