Using a virtual extensometer, it was found that irradiation with a pulsed electron beam (18 keV, 15 J/cm 2 , 200 μs, 3 pulses, 0.3 s −1 ) leads to an increase in the strength properties of the hypoeutectic silumin samples by 30%. The deformation curves in the coordinates «σ-ε» and «σ - √ε» did not reveal inflection points that characterize the stages of deformation transformation of the material. This indicates that the transitions from stage to stage in this class of materials are blurred.
