| Summary: | Заглавие с экрана The irradiation of silumin with the hypereutectic composition (18-20 wt.% Si) by an intense pulsed electron beam in the melting mode of the surface layer was performed. It had been established that the irradiation of surface of a cast hypereutectic silumin specimens with a pulsed electron beam is accompanied by a multiple increase in strength and plastic properties of the material. It had been shown that the main reason for increase in the mechanical properties of silumin is the formation of an extended (up to 100 [mu]m thick) surface layer with a submicro-nanocrystalline structure, as a result of high-speed crystallization, initiated by irradiation with a pulsed electron beam. |
