RETRACTED: Atomic scale interfacial and compositional characteristics of the σ and γ phases of Ni-based single-crystal superalloys

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the authors and the Coordinating Editor.The calculations at the core of the article were based on an assumption that the crystal structure of the σ phase was incorrectly approximated. Further research and intensive discussion with colleagues has helped the authors to realize the assumptions made with their calculations cannot stand. This precludes from determining the site occupancy of each element and the segregation in the σ phase cannot be correctly approximated as a multicomponent phase by W8Cr10NiCo11 in the calculations.The authors have expressed deep regret and have asked for retraction of their article.
