Summary:Title screen
Methods of optical, atomic-force, and transmission and scanning electron microscopy, as well as X-ray diffraction analysis have been used to study the effect of electron-beam treatment on the surface morphology and structure of titanium of grade VT1-0. It has been shown that irradiation by three electron pulses with an energy density in the beam of W = 12–24 J/cm2 and a pulse duration of 50 [mikro]s leads to the formation of VT1-0 samples of a multilayer structure in the surface layers that consist of fine particles of the [alpha] phase, which have a subgrain structure, and of the underlying coarse grains, which contain ?’ martensitic phase. The influence of the density of energy of the electron beam on the hardness and the magnitude of microand macrostresses that develop in the modified surface layer has been demonstrated. The results of calculating the thermal fields that appear in the process of treatment by electron beam are presented.
