Description

Irradiation of large-grained Zircaloy-2 (Zy) and Zr-2.5Nb (ZN) with 1.5 MeV Ar+ ions to fluences of ∼ 1020/m2 ≡ 10--30 dpa at 50, 300 and 420 C, leads to enhanced α-phase Fe dissolution. Electron microprobe analyses showed α-phase Fe levels of 25--1,500 ppma, compared to equivalent, non-irradiated state values of ∼ 70 ppma. In ZN the β-phase Fe levels fell from about 6,000 to 3,500 ppma: this result accords, qualitatively, with the loss of Fe from the β-phase following in-service neutron irradiation. Concentration vs depth measurements for Zy showed higher Fe levels towards the surface. Limited data for Ni in Zy show similar behavior
