This work comprises a study of the influence of the energy density E s of the low-energy high-current electron beam (LEHCEB) exposure on the morphology of surface and mechanical properties of the surface layer of nickel titanium alloy (NiTi alloy). It was found that the formation of crater-like relief on the surface of NiTi alloy after electron beam treatment is determined by the structure and distribution of the particles of second and impurity phases. The mechanical properties in a modified surface layer of no more than ∼ 500 nm thickness change at different values of the energy density E s of electron beam.
