Effects of Cold Deformation and Electron Irradiations on Deuterium Desorption Temperature Range from Zr – 1 %Nb Alloy

Abstract

The explored warm-up ranges of desorption ion-implanted deuterium from Zr – 1 %Nb alloy, with different structure: after crystallization from melt, plastic deformation and irradiations electron. Cool deformation under 300 K Zr – 1 %Nb alloy with degree   3.9 has allowed to reach the nanostructure conditions in alloy with average size crystallite d  61 nm, high three-dimensional concentration of the borders (~ 3,4 %) and significant level microstrain that in spectrum of thermodesorption ion-implanted deuterium was shown as additional low temperature area thermodesorption deuterium within the range of the temperature 770-1000 K. Irradiation electron to energy 10 MeV by fluence ~ 6 × 1017 cm – 2 has brought about active development of the revocable processes in nanostructure alloy: reduction of the average grain size d  58 nm, increase to concentrations of the borders (~ 8,8 %) and appearance additional peaks in spectrum of thermodesorption deuterium with the temperature 700 and 800 K and, accordingly, increase the warmup range desorption deuterium toward reduction of the temperature.
