Silumin AK10M2N is studied in a cast condition and after irradiation with a pulsed electron beam (17 keV, 50 J/cm2, 3 pulses, 100 sec, 0.3 sec –1). Elemental and phase compositions of the alloy are determined. Structure and the fracture surfaces after uniaxial tension of flat specimens in an INSTRON 3386 machine at a constant rate are studied by scanning electron microscopy and transmission electron diffraction microscopy. It is shown that irradiation of alloy AK10M2N with a pulsed electron beam is accompanied by fusion of a comparatively thin (up to 100 μm) surface layer. Subsequent high-speed crystallization yields a multiphase submicro- and nanocrystalline structure of cellular crystallization. Cast alloy irradiation with an electron beam increases ultimate strength by a factor of 1.8 and elongation by a factor of 2.2. The main causes of this effect are determined.
