Cyclic Corrosion and Chlorination of an FeCrAl Alloy in the Presence of KCl [PDF]

Oxidation of Metals, 2015
The KCl-induced corrosion of the FeCrAl alloy Kanthal® APMT in an O2 + N2 + H2O environment was studied at 600 °C. The samples were pre-oxidized prior to exposure in order to investigate the protective nature of alumina scales in the present environment. The microstructure and composition of the corroded surface was investigated in detail.

Impact toughness of commercial and model FeCrAl alloys

Materials Science and Engineering: A, 2018
Abstract FeCrAl alloys are under development as possible candidate materials of accident-tolerant fuel cladding in light water reactors. In this study, the cracking resistance of FeCrAl alloys was evaluated using half-size Charpy impact tests at temperatures ranging from room temperature to 600 °C.

Hydrogen permeation in FeCrAl alloys for LWR cladding application [PDF]

Journal of Nuclear Materials, 2015
Abstract FeCrAl, an advanced oxidation-resistant iron-based alloy class, is a highly prevalent candidate as an accident-tolerant fuel cladding material. Compared with traditional zirconium alloy fuel cladding, increased tritium permeation through FeCrAl fuel cladding to the primary coolant is expected, raising potential safety concerns. In this study,

Enhancement of hardness and high-temperature oxidation resistance of Cr/FeCrAl dual-layer plasma-sprayed coating on Zr substrate by post-processing

Journal of Materials Research and Technology
A Cr/FeCrAl dual-layer coating was deposited on a Zr alloy substrate using atmospheric plasma spraying (APS) to potentially consider the requirement of both loss-of-coolant accidents (LOCA) and normal operating conditions of nuclear cladding cores.

Optimizing chemistry for designing oxidation resistant FeCrAl alloys

MRS Advances, 2023
AbstractTraditionally, FeCrAl alloys played an important role in high-temperature applications due to their ability to form a passive Al oxide film at temperatures above ~ 800 °C. Recently, FeCrAl alloys became of interest for the application of accident tolerant nuclear fuel cladding. This study covers work done at GE Research for better understanding
