Влияние водорода на релаксационные процессы в циркониевом сплаве

Abstract

A calculation is made of the ohmic and phonon relaxation time in hydrogenated zirconium. The law of charge conservation and the dependence of the electrical resistivity of a zirconium alloy on the concentration of hydrogen were used as the basis for the analysis. Analysis of the relaxation time for various concentrations of hydrogen in a zirconium alloy at different temperatures makes it possible to use this parameter to estimate the hydrogen content. It is shown that the relaxation time decreases with increasing hydrogen concentration in zirconium. This is due to an increase in the scattering of charges (protons and electrons) on defects caused by hydrogen saturation.
