摘要

Abstract

Severe plastic deformation (SPD) is a common method to fabricate nano-grained metals. However for Zr

a structural metal for nuclear applications

obtaining a nanoscale grain structure via SPD has been problematic due to deformation twinning and phase transformations. Here

nanostructured hcp Zr is fabricated through a refinement process via the introduction of a biphase interface. Despite mechanical and thermal conditions known to chemically mix Zr and Nb

no intermixing is observed and the heterophase interfaces appear resistant to phase transformations and twinning. Increasing the density of chemically sharp Zr–Nb interfaces is a very different refinement mechanism than substructure development

stacking fault formation

or alloying.
