Abstract Scope |
This work explores the development of a heterogeneous nanostructured material synthesized via sputtering and by leveraging abnormal recrystallization. A sputtered nanotwinned Inconel 725 film with a heterogeneous distribution of stored energy was heat treated at 730°C, creating a unique combination of grain sizes and morphologies that were observed throughout the thickness of the material. Nanotwinned materials have been shown to exhibit exceptional mechanical and thermal properties due to a high density of coherent twin boundaries. As a result, there has been interest in investigating the effects of a nanotwinned structure on superalloys, which typically achieve strengthening through second phase or precipitate formation. From the experimental observations and the detailed analysis performed in this study, this methodology can be utilized to further expand the design space of current heterogeneous nanostructured materials |
