Abstract

The Mo₂Zr phase has been identified as a major interaction product at the interface of U-10Mo and Zr. Transmission electron microscopy in-situ irradiation with Kr ions at 200 °C with doses up to 2.0E + 16 ions/cm² was carried out to investigate the radiation stability of the Mo₂Zr. The Mo₂Zr undergoes a radiation-induced structural change, from a large cubic (cF24) to a small cubic (cI2), along with an estimated 11.2% volume contraction without changing its composition. The structural change begins at irradiation dose below 1.0E + 14 ions/cm². The transformed Mo₂Zr phase demonstrates exceptional radiation tolerance with the development of dislocations without bubble formation.
