摘要

Effect of helium and hydrogen synergy on vacancy migration energy (E-m(v)) and microstructural evolution of Fe-10Cr model alloy were investigated by single-He, H and sequential-(He + H) ion pre-implantation and subsequent in-situ electron irradiation at different temperature. Growth rates of irradiation induced dislocation loops were experimentally measured at temperatures ranging from 573 to 773 K to calculate E-m(v). The loop's size increased as a function of irradiation dose. Moreover, pre-implantation with sequential-(He + H) ion showed an increase in the temperature dependence of the loop growth rate compared to implantation with single He and H. The E-m(v) were determined to be 1.4-1.5 eV in single He and H implanted sample. In-situ electron irradiation experimental results indicated that the E-m(v) be increased due to He and H synergy. Foil surface effect on the calculation of the migration energy has been considered also by discussing a new derivation. This synergic effect of He and H on the evolution of dislocation loop and the mobility of vacancy have been discussed. (C) 2019 Elsevier B.V. All rights reserved.
