In the present work has been carried out the treatment of silumin by high-intensity electron beam with different density of the input energy. The structure and phase composition of surface layer have been studied by the methods of X-ray diffraction and electron microscopy both scanning and diffraction transmission. The mechanisms are responsible for improvement of properties of modified material have been revealed. It has been shown that electron beam treatment of silumin is accompanied by the formation of multilayer submicro-and nanocrystalline structure and result in increasing the microhardness of the surface layer (towards the core) is ~ 3.5 times, the Young's modulus in a ~ 1.4 times, the ultimate bending strength (in ~ 1.2 times) and tensile strength (in ~ 1.4 times), the bending plastic limit (in ~ 1.2 times) and tensile (in ~ 1.8 times).

The paper presents the results of a study of the effect of irradiation of the surface of a hypoeutectic silumin with a pulsed electron beam on the mechanical properties of the material. Silumin grade AK5M2 (Al–(4.0–6.0)Si–1.3Fe–0.5Mn–0.5Ni–0.2Ti–2.3Cu–0.8Mg–1.5Zn) was used as the research material. To carry out uniaxial tensile deformation, two-sided proportional samples with heads were made. The results of studying the evolution of deformation fields of layered composites silumin/CFRP for uniaxial tension based on irradiated silumin are also presented. The carbon fiber is made of a filler – carbon unidirectional fabric FibARM Tape-230 – and a binder – a two-component epoxy compound FibARM Resin 530. The fracture surface of the samples was studied using scanning electron microscopy techniques. The dependences of the maximum and minimum values of strains in the localizers on the sample surface on the averaged strains over the working area of the sample are plotted. An increase (relative to silumin in the initial state) in the strength and plastic properties of both samples of irradiated silumin and of the silumin/CFRP composite was determined. A sawtooth character of the deformation curve of uniaxial tension of the composite material silumin/carbon fiber with a pre-irradiated surface of the silumin plate is revealed.

EVOLUTION OF THE AISI 5135 STEEL STRUCTURE AND PROPERTIES UNDER ELION NITRIDING IN LOW-PRESSURE GAS DISCHARGE

A method and experiments for nitride AISI 5135 steel with simultaneous heating of the samples by the electron component of plasma are described. A nitriding regime that makes it possible to form a hardened layer up to 240 μm thick is explained. It is shown that the microhardness of the surface layer increases with an increase in the nitriding temperature. It is further demonstrated that the microhardness correlates with the relative content of the nitride phase. The maximum microhardness was recorded in the subsurface layer at the depth of ≈ 10 μm regardless of the nitriding temperature. The wear resistance depends on the concentration of nitrogen atoms in the α-Fe crystal structure; the saturation of the α-Fe crystal structure with nitrogen contributes to an increase in material wear under dry friction.

A comparative analysis of the microstructure and durability of hard-alloy plates treated with high-energy pulsed electron beam generated from the plasma of argon or xenon in steel cutting was conducted. It is shown that the choice of the plasma gas to generate electron from the cathode plasma-filled setting for pulsed electron-beam irradiation has a significant influence on the formation of structural-phase state in the surface layer and the durability of hard-alloy plates in steel cutting.
