Effects of Cold Deformation and Electron Irradiations on Deuterium Desorption Temperature Range from Zr–1%Nb AlloyKeywords: Surface engineering , Plasma technologies , Ion technologies , Advanced plasma and ion sources , Plasma-surface interaction Abstract: The explored warm-up ranges of desorption ion-implanted deuterium from Zr-1%Nb alloy, with differ-ent structure: after crystallization from melt, plastic deformation and irradiations electron. Cool defor-mation 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 tempera-ture 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 warm-up range desorption deuterium toward reduction of the temperature.
