In situ Observation of Defect Annihilation in Kr Ion-Irradiated Bulk Fe/Amorphous-Fe2Zr Nanocomposite Alloy
Enhanced irradiation tolerance in crystalline multilayers has received significant attention lately. However
little is known on the irradiation response of crystal/amorphous nanolayers. We report on
in situ
Kr ion irradiation studies of a bulk Fe

nanocomposite alloy. Irradiation resulted in amorphization of Fe

Zr and formed crystal/amorphous nanolayers. α-Fe layers exhibited drastically lower defect density and size than those in large α-Fe grains.
In situ
video revealed that mobile dislocation loops in α-Fe layers were confined by the crystal/amorphous interfaces and kept migrating to annihilate other defects. This study provides new insights on the design of irradiation-tolerant crystal/amorphous nanocomposites.
