TL;DR: In this paper, two distinct starting microstructures of Zr-2.5 wt% Nb have been used: (1) single-phase α hcp martensitic structure; and (2) two-phase, 10% bcc β and rest hcp α, Widmanstatten structure.

TL;DR: In this article, the oxidation behavior of 304L stainless steel (SS) subjected to different surface finishing (machining and grinding) operations was followed in situ by contact electric resistance (CER) and electrochemical impedance spectroscopy (EIS) measurements using controlled distance electrochemistry (CDE) technique in high purity water (conductivity

TL;DR: In this paper, the authors made an effort to systematically characterize the textural changes during the fabrication stages of the Indian pressurized heavy water reactors (PHWR) and made an attempt to characterize the texture changes during hot extrusion and annealing.

TL;DR: In this paper, the effect of partial boiling on oxidation behavior was assessed in terms of change in the level of dissolved oxygen (DO) in static autoclaves, and the results clearly demonstrated that the oxidation behavior of Zircaloy-2 is quite immune to the level, while Zr-Nb alloys showed very different oxidation behaviour with change in dissolved oxygen level.

TL;DR: The effects of Fe addition in the range of 300-1250-ppm in cold worked stress-relieved Zr-2.5Nb pressure tube on oxidation and hydrogen pick up behavior have been studied after 415°C steam autoclaving as discussed by the authors.
