| Abstract Scope |
Due to their excellent resistance to high temperature steam oxidation, FeCrAl alloys are excellent candidates for Accident Tolerant Fuel (ATF) cladding material. Although FeCrAl alloys have been used in industry for several decades, historical applications have been high temperature operation environments and therefore more work is needed to understand the mechanical properties of these alloys at room temperature and light water reactor operating conditions. It has been shown that non-optimized FeCrAl alloys are susceptible to cracking and brittle failures which can significantly affect fracture and impact toughness, strain to failure, and alloy strength. This can cause concerns with fabrication, transport, and stress corrosion cracking in these alloys. Development work on commercial FeCrAl alloys has shown that a fine-grained microstructure can significantly improve mechanical properties of these alloys. This study will go through historical development and optimization of FeCrAl microstructures, and the impact of this microstructure on various mechanical properties. |
