Neutron Irradiation-Induced Defect Structures in Zirconium

Source

A transmission electron microscope (TEM) was used to study the neutron irradiation-induced defect structures in zirconium from various sources irradiated to fluences up to 1.3 × 1025 neutrons (n)/m-2 > 0.1 MeV and temperatures in the range 478 to 823 K. Below 673 K the predominant form of damage consists of ⅓ 〈1120〉 dislocation loops. At higher irradiation temperatures, depending on specimen purity, the defects may include faulted ⅙ 〈2023〉 loops and voids in addition to the perfect ⅓〈1120〉 loops. The temperature regime of the stability of the various defects was defined. Quantitative measurements showing the effect of irradiation temperature and specimen purity are presented and discussed.
