Modification of titanium alloy parts properties by intensive current electron beams

The influence of irradiation regimes by low energy intensive current electron beams of microsecond duration on chemical composition and phase-structural state of titanium alloy parts surface layers. It is shown that this treatment enables: to purify surface of details from the oxygen and carbon impurities; to improve the element distributions homogeneity in a depth; to decrease roughness of surface up to 0.05–0.07 µm; to modify the phase composition and structure of material in surface layer up to 10 µm thickness. In addition, the fatigue life can be increased in 80 times.
