Phase Transitions in Beta Ti and Beta Zr Alloys

Abstract

Titanium alloys and zirconium alloys can occur in different crystalline arrangements - phases - depending on the composition and processing of the material. While the phase transformations in titanium alloys have already been, the phase transformations in zirconium are significantly less explored.

Zirconium is mainly used in nuclear energy due to its low effective neutron capture cross section. Alloys that contain alloying elements to maintain the beta phase of the material are referred to as metastable beta alloys.

Phase transformations in binary Ti-Mo alloys have been studied in detail with the use of in-situ and ex-situ methods. Acquired knowledge was used for the study of Zr-Nb binary alloys.
