Description
Summary:Transmission electron microscopy (TEM), optical metallography, and electron probe microanalysis (EPMA) were used to study the chemical composition and microstructure of surface layers in blades made of VT6 alloy treated by a high-current pulsed electron beam at the energy density of the beam W = 18–20 J/cm 2 . It is shown that the melting regime of irradiation leads to formation of a high-strength surface layer of up to 25 μm in thickness with a fine substructure. The increase in mechanical properties of the modified layer is caused by formation of fine α′- and α″-martensite plates oriented almost parallel to the blade surface.
