| Abstract Scope |
FeCrAl alloys have shown great promise for use as accident tolerant fuel cladding due to their excellent high temperature steam oxidation resistance, good hydrothermal corrosion resistance, and desirable mechanical properties. One concern, however, is the formation of α’, a Cr enriched phase which precipitates in Cr bearing ferritic alloys at temperatures around or below 500°C. This presentation will give an overview of GE’s development of FeCrAl alloys and future plans to combine experiments and regression analysis using machine learning to optimize alloy chemistry. Considerations of microstructure and chemistry on corrosion, mechanical properties, and phase stability will be discussed. Attention will also be given to the effects of radiation on such properties. |
