英文摘要	Helium nanobubbles created in nickel foil under helium ion irradiation are studied using the combination of small-angle X-ray scattering (SAXS) measurement and transmission electron microscopy (TEM) characterization. The log-normal distribution of bubble sizes obtained by SAXS agrees rather well with the TEM results. Under the tensile stress, SAXS experiments were carried out to follow in situ the evolution of helium nanobubbles. A detailed analysis revealed that the bubbles performed coalescence via the elongation in the direction of tensile stress loading. Our finding demonstrated that bubble "deformation and coalescence" mechanism was also applicable in bubble growth under external stress. (C) 2018 Acta Materialia Inc. Published by Elsevier Ltd.
