摘要：

Effect of pulsed electron beam exposure on the creep of the Zr-Nb-H system alloys with the hydrogen content of 0.004 and 0.25 wt % was studied for the creep rates in the interval 10(-7)-10(-5) s(-) at 673 K. Pulsed electron beam irradiation is found to result in a decrease in the rate of steady creep for indicated alloys. The dependence of the steady creep rate on the strain for investigated alloys of the Zr-1Nb-H system before and after irradiation is satisfactorily described by the creep power law with the values of stress sensitivity index corresponding to the creep realized by dislocation glide.
