Some observations on Zr-O solid solutions with a microprobe and by electron microscopy
TLDR
In this article, the presence of the ordered phase Zr 3 O in thin foils of oxidized zirconium was established by selected area diffraction, and the hardness was measured in the diffusion zone and the non-linear relation between hardness and oxygen concentration was derived.About:

Zirconium alloys for supercritical water reactor applications : Challenges and possibilities
Arthur T. Motta,Aylin Yilmazbayhan,Marcelo J. Gomes da Silva,Robert J. Comstock,Gary S. Was,Eric Gartner,Quinja Peng,Yong Hwan Jeong,Jeong Yong Park +8 more
TL;DR: In this paper, the corrosion behavior of model Zr-based alloys at 500°C is assessed by long term (up to 400 days) corrosion testing in an effort to evaluate their potential for use in the supercritical water reactor and to assess the influence of alloying elements on corrosion behavior.

Thermally activated deformation of Zircaloy-4
TL;DR: In this paper, tensile tests were carried out on Zircaloy-4 over the temperature range 298-798 K and the authors found that the peak in activation volume was attributed to the negative value of the strain rate sensitive solute strengthening term M and that the mechanism based on the non-conservative motion of jogs appeared to be more favored as the basic rate controlling mechanism.

Oxidation and hydrogen uptake in zirconium, Zircaloy-2 and Zircaloy-4: Computational thermodynamics and ab initio calculations
TL;DR: In this article, a special emphasis was placed upon the role of zirconium suboxides in hydrogen uptake reduction and the atomic mechanisms of oxidation, and computational thermodynamics calculations were conducted concurrently with first-principles atomistic modeling.

X-RAY STUDIES ON SOLID SOLUTIONS OF OXYGEN IN /CAP alpha/-ZIRCONIUM
B. Holmberg,T. Dagerhamn +1 more
TL;DR: In this article, the authors investigated the solubility of oxygen in alpha-zirconium in the temperature region, 400-800 deg C, by x-ray methods and showed that with increasing oxygen content, the length of the c axis increases over the entire solubability range while that of the a axis passes through a maximum at the composition ZrO/sub 0.4/sub 1.2/sub 5/.
