The effect of electron beam treatment on hydrogen sorption ability of commercially pure titanium

The surface morphology and the microstructure of commercially pure titanium specimens subjected to electron beam treatment with energy density varying from 12 to 25 J/cm2 were studied using atomic force microscopy and transmission electron microscopy as well as X-ray diffraction analysis. Lamellar α-phase structure of a thin surface layer of the specimens resulted from the treatment was shown to have a great effect on hydrogen sorption ability of the material as well as on hydrogen arrangement in titanium crystal lattice.
