Microstructural understanding of the oxidation of an austenitic stainless steel in high-temperature steam through advanced characterization
Zhao Shen,David Tweddle,Hongbing Yu,Guanze He,Aakash Varambhia,Phani Karamched,Felix Hofmann,Angus J. Wilkinson,Michael P. Moody,Lefu Zhang,Sergio Lozano-Perez +10 more
TL;DR: In this paper, the surface oxide film formed on an Fe-17Cr-9Ni stainless steel after exposure to high-temperature steam has been studied in detail, and the characterization results obtained in this study reveal that the inner oxide layer actually consists of two phases Fe-Ni austenite and FeCr2O4 oxide, which formed due to internal oxidation.
Journal ArticleDOI
New insights into the oxidation mechanisms of a Ferritic-Martensitic steel in high-temperature steam
Zhao Shen,Kai Chen,Hongbing Yu,Benjamin M. Jenkins,Yanru Ren,Naganand Saravanan,Guanze He,Xiaonan Luo,Paul A. J. Bagot,Michael P. Moody,Lefu Zhang,Sergio Lozano-Perez +11 more
TL;DR: The microstructure of the surface oxide film formed on an Fe-9Cr Ferritic-Martensitic (F-M) steel after exposure to deaerated high-temperature steam at 600°C for 100h has been analyzed in detail by advanced characterization techniques.
Journal ArticleDOI
Characterization of the crack initiation and propagation in Alloy 600 with a cold-worked surface
TL;DR: In this paper, the crack initiation on a cold-worked surface of Alloy 600, exposed to simulated pressurized water reactor primary water, was mechanistically studied through high-resolution characterization.
Journal ArticleDOI
Mechanism of the α-Zr to hexagonal-ZrO transformation and its impact on the corrosion performance of nuclear Zr alloys
Junliang Liu,Hongbing Yu,Phani Karamched,Jing Hu,Guanze He,Daniel Goran,Gareth M. Hughes,Angus J. Wilkinson,Sergio Lozano-Perez,Chris R. M. Grovenor +9 more
TL;DR: In this article, the formation of hexagonal-ZrO suboxide during aqueous corrosion of αZr alloys was investigated and it was shown to be a paraequilibrium displacive transformation with the rate controlled by oxygen diffusion.
Journal ArticleDOI
Investigating the stability of second phase particles in Zr-Nb alloys under irradiation
Guanze He,Junliang Liu,Kexue Li,Jing Hu,Anamul H. Mir,Sergio Lozano-Perez,Chris R. M. Grovenor +6 more
TL;DR: In this paper, the stability of the second phase particle (SPP) in two types of Zr-Nb alloys was studied by in-situ heavy ion irradiation in a transmission electron microscope (TEM), combined with ex situ analysis by energy dispersive x-ray spectroscopy (EDX).
