Abstract

The α-β phase transformation behavior of Zr-2.5 Nb has been characterized in real time during an in-situ neutron diffraction experiment. The Zr-2.5 Nb material in the current study, at room temperature, consists of α-Zr phase (hcp) and two β phases (bcc), a Nb rich β-Nb phase and retained, Zr rich, β-Zr (Nb) phase. Other than the Burgers and Potter orientation relationships between (002) hcp and (110) bcc, this is the first time the transformation from retained Zr rich β-Zr (Nb) phase to β− Zr with increasing temperature has been reported in the literature. It is suggested that this is related to a dynamic equilibrium of the solubility of Nb atoms in the Zr bcc unit cells.
