Title: Investigations of deformation-induced δ → ζ phase transformation in zirconium hydride by in situ high-energy X-ray diffraction

Here in situ high-energy X-ray diffraction (HE-XRD) was used to study the micromechanical behavior of Zircaloy-4 during tensile loading, revealing for the first time a deformation-induced phase transformation from δ-hydride to ζ-Zr 2H in the hydride at a critical stress of approximately 370 MPa.
