摘要Vacancies and voids evolution within the nanoporous (np) AuAg(Pt) ligaments during thermal coarsening was investigated by positron annihilation spectroscopy and scanning electron microscopy (SEM). Partially dealloyed ternary np AuAg(Pt) samples with 5-8 nm ligaments were prepared by electrochemical dealloying of (Au0.95Pt0.05)(25)Ag-75 ingots. Positron lifetime experiments demonstrated that nano-ligaments are stable against coarsening below 320 degrees C. Vacancies play an essential role during the coarsening process. Lifetime parameters changed above 320 degrees C, associated with a large number of vacancies and divacancies formed via coarsening with large enclosed voids formed at the same time. SEM images demonstrate ligaments growing non uniformly during thermal coarsening. (C) 2016 Elsevier Ltd. All rights reserved.
