Mechanisms for Zr deformation, such as the activa-tion energy for Zircaloy-4 creep and the stress exponent for Zircaloy-4 creep, were established in this work and were in agreement with literature values. Comparisons to Cr coated tubing showed that Cr coatings have similar mechanisms for cladding deformation as uncoated material, yet the rupture conditions were roughly 80C higher with Cr coated Zircaloy-4. Cladding segment yield stress and ultimate tensile stress were also extracted from the in-situ strain data, showing that Cr coated tubing has roughly 80C higher temperatures in mechanical performance or roughly a 40 MPa increase in yield stress compared to the uncoated baseline. Post-test characterization showed that the operating temperature governed the microstructure characteristics, and that the Cr coating did not impact the morphology of the Zircaloy-4 tubing.
