Observation of the δ to ε Zr‐hydride transition by in‐situ synchrotron X‐ray diffraction

Abstract

We investigate the formation and dissolution of hydrides in commercially pure zirconium powder in‐situ using high‐energy synchrotron X‐ray radiation. Experimental results showed a continuous phase transition between the δ and ε zirconium hydride phases with indication of a second order phase transformation.
