Atomic Mixing Induced by Ion Irradiation of V/Cu Multilayers

更新时间:2023-05-28

【摘要】Bulk Cu/V multilayers simultaneously possess high strength and excellent radiation resistance thanks to their high density of interfaces.Irradiation-induced atomic mixing of Cu/V multilayers has been less investigated.Here,we investigate the ion irradiation of bulk Cu/V multilayers exposed to H2+ or He+ ions at 350℃.The microstructure and elemental distribution are investigated by transmission electron microscopy and energy dispersive x-ray spectroscopy.Facetted bubbles and atomic mixing are observed after ion irradiation.The possible mechanisms of irradiation-induced atomic mixing are discussed.
