Evaluating the Use of Phosphate to Mitigate Caustic-PbSCC of Alloy 690TT

Product Number: ED22-17293-SG

Author: Giulia B. Mazzei, Jonathan Duff,D.A. Horner, M.Grace Burke, Fabio Scenini

PbSCC of Ni-base alloys is active over a wide range of environmental conditions but for the higher Cr content Alloys 800 and 690 only under abnormal crevice environment of high or low pH that can occur in the secondary side of Pressurized Water Nuclear Reactors (PWRs). Several experimental campaigns have aimed at understanding this phenomenon, concluding that PbSCC can develop in both acidic and caustic solutions, for low and high concentration of Pb, across a wide electrochemical potential range and in presence of chlorides contaminants.

Intergranular Oxidation and Oxygen Transport in Ni-20Cr During Exposure to Model Dry and Wet Oxidation Environments

Product Number: ED22-17329-SG

Author: Martin Weiser, Daniel K. Schreiber, Karen Kruska, Mark H. Engelhard, Matthew J. Olszta

Publication Date: 2022

The austenitic Ni-base Alloy 600 has been extensively used as structural material in primary water reactors (PWR). Despite good resistance against general corrosion in water-cooled nuclear power reactors, the material has been susceptible to stress corrosion cracking (SCC). These observations have led to ongoing discussions of the underlying embrittlement mechanism(s). Internal oxidation of the grain boundary (GB) at typical operating temperatures is one such mechanism, although debate continues on the exact mechanisms at play.

Investigation on Metal Dusting Corrosion Phenomena Over Incoloy 800

Product Number: 51317--9439-SG

ISBN: 9439 2017 CP

Author: Xiaoyang Guo

Publication Date: 2017

$20.00

UNS N08800 alloy coupons were prepared, polished and oxidized in diluted steam at 540 ºC. Formation of carbon on the surface of the pre-oxidized samples was investigated by exposure to reducing, highly carburizing atmosphere (CO in Ar) at 20 bar and varying temperature (550- 750 ºC).

Microstructure Characterization Of Additively Manufactured Alloy 718

Product Number: 51323-19419-SG

Author: Liu Cao, Dian Li, Sydney Fields, Yufeng Zheng

Publication Date: 2023

$20.00

Alloy UNS N07718 (hereafter abbreviated as 718) is one of the most versatile precipitation-hardened nickel-based corrosion-resistant alloys (CRAs) used for both surface and sub-sea components in oil and gas production service. API 6ACRA provides heat treatment windows and acceptance criteria for 718 in these oil and gas production environments, in which the heat treatment is intended to homogenize the microstructure and obtain the correct microstructure for targeting the desired mechanical properties. For fabricating high temperature materials via additive manufacturing (AM), alloy 718 is a primary focus due to its widespread applications in the past 60 years and excellent weldability in either age hardened or annealed condition.
