Abstract Scope APMT is a promising FeCrAl-based alloy suitable as an accident tolerant fuel (ATF) cladding due to its excellent corrosion resistance. Here, characterization of the powder metallurgy APMT alloy neutron irradiated to 1.8 dpa at 382 C has been performed. On-zone STEM imaging revealed that radiation-induced dislocation loops with a Burgers vector of a⁄2 〈100〉 or a〈100〉 and black dots tended to agglomerate in the vicinity of reactive-element particles. The density and size of these loops reduced with increased distance between the particle-matrix interfaces. In addition, high-resolution energy-dispersive X-ray spectroscopy mapping was used to determine the particles to be either Y- or Hf- rich, as well as to detect the radial distribution of radiation-enhanced α' phase near these reactive element particles. A high density of randomly distributed Cr-rich α' phase was found regardless of the presence of particles. Results from this study provide insight into microstructures that affect APMT’s radiation tolerance.
