Migration Barriers and Evolution of Mechanical Properties of Oxide Nanoclusters Containing Helium

  • Thomas Danielson (a1) and Celine Hin (a1) (a2)

Abstract

High number densities of complex oxide nanoclusters in nanostructured ferritic alloys have been shown to act as effective trapping sites for the transmutation product helium. Density functional theory has been used to investigate the evolution of the mechanical properties of oxide nanoclusters as helium concentration increases. The migration barrier and migration path of helium in the oxide has also been tested in order to make a comparison with the barriers in BCC iron and offer insight to the helium trapping mechanisms of the oxides.
