description: The object of the study is microdendrites of silver and copper, which are irradiated by a beam of accelerated low-energy (up to 50 keV) electrons. Electrons of this kind are able to significantly change the structure of the near-surface layers of the material, since the depth of their penetration is small. This work is devoted to the study of changes in the surface structure of silver and copper microdendrites resulting from electron irradiation. Electronic irradiation of metal samples with microdendrites of silver and copper on the surface was carried out in the laboratory of "Physics of Interaction of Radiation with matter" at Peter the Great St. Petersburg Polytechnic University. Structural changes in the surface of the samples after electron irradiation were investigated using scanning electron microscopy. The obtained results were processed and processed using smartSEM and Gwyddion application programs. It was revealed and shown that irradiation with an electron beam with energies of 10 and 30 keV and doses of 20 and 50 Âµl/cm2 of samples with microdendrites leads to a restructuring of the microcrystalline structure with a change in fractal dimension.
