Metastable phases and nanocrystalline-forming ability (NFA) of melt-quenched Ni-rich (Zr, Hf)-Ni alloys

Research output: Contribution to journalArticle

Abstract

In this paper, the basic principles of and some recent advances in rapid solidification are briefly considered, with main emphasis on the formation of single-phase metastable states during meltquenching in Ni-rich Zr-Ni and Hf-Ni alloys. Factors controlling nanocrystalline-forming ability are discussed in detail, with particular view on the preparation of single-phase nanocrystalline alloys by the melt-quenching process.
