Abstract
The nano- and ultradisperse grain structure has been formed by the method of electron-beam welding on the electron accelerator of tungsten and chromium carbides and by the following pulse treatment low-energy electrons. This structure has been fi lled with the nano- sized pore system. It has been shown that nanohardness and modulus of elasticity reach their high values in the secondary pulse-affected zone. The formation of the nano-sized structures with a well-developed system of pores in the surface layer prevents brittle surface fractures.
