Arrest of He bubble growth in CuNb multilayer nanocomposites Academic Article

abstract

• Transmission electron microscopy on Cu-Nb multilayer nanocomposites implanted with 1017 cm-2 of 33 keV 4He+ at 763 K revealed uniformly dispersed He bubbles of 1-2 nm diameter in Nb and a broad distribution of larger ones in Cu. Bubbles in Cu were confined by the neighboring Nb, limiting their size normal to Cu-Nb interfaces to the Cu layer. The conditions under which layered composite morphology may be used to control He bubble distributions in materials under irradiation are discussed. 2007 Acta Materialia Inc.
