Microstructure changes in Zr-1Nb alloy after pulsed electron beam surface modification and hydrogenation

Abstract

In this paper the results of experimental study of microstructure changes in Zr-1Nb alloy after low energy high current pulsed electron beam surface modification and hydrogenation are discussed. Surface treatment was carried out with energy density equal from 5 to 25J/cm² and impulses number equal from 1 to 5. Subsequent hydrogenation was carried out at temperature equal to 350°C until reaching the hydrogen concentration of 0.05wt.%. The structure was analyzed by X-ray diffraction, transmission electron microscopy and by means of electron-positron techniques.
