Hardening of the Surface Layer of Silumin by Electron Beam

Abstract:

In the present work has been carried out the treatment of silumin by high-intensity electron beam with different density of the input energy. The structure and phase composition of surface layer have been studied by the methods of X-ray diffraction and electron microscopy both scanning and diffraction transmission. The mechanisms are responsible for improvement of properties of modified material have been revealed. It has been shown that electron beam treatment of silumin is accompanied by the formation of multilayer submicro-and nanocrystalline structure and result in increasing the microhardness of the surface layer (towards the core) is ~ 3.5 times, the Young's modulus in a ~ 1.4 times, the ultimate bending strength (in ~ 1.2 times) and tensile strength (in ~ 1.4 times), the bending plastic limit (in ~ 1.2 times) and tensile (in ~ 1.8 times).
