摘要：
The work presents the results of studying the effect of irradiation of the surface of hypoeutectic silumin with a pulsed electron beam on the mechanical properties of the material. Silumin of grade AK5M2 (Al-(4.0-6.0) Si-1.3 Fe-0.5 Mn-0.5 Ni-0.2 Ti-2.3 Cu-0.8 Mg-1.5 Zn) is used as a test material. To carry out uniaxial tensile deformation, double-sided proportional samples with heads are made. The results of studying the evolution of strain fields of layered composites silumin/carbon-fiber-reinforced plastic (CFRP) based on irradiated silumin in uniaxial tension are also presented. The carbon fiber is made of a filler (FibARM Tape-230 unidirectional carbon fabric) and a binder (FibARM Resin 530 two-component epoxy compound). The fracture surface of the samples is 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 is determined. The sawtooth character of the deformation curve of uniaxial tension of the silumin/CFRP composite material with a pre irradiated surface of the silumin plate is revealed.
