Low temperature recovery of radiation damage in vanadium

PDF Version Also Available for Download.

Description

Some kind of order may emerge from the numerous anomalies in the low- temperature recovery of irradiated V if it is assumed that Stage I (first recovery by interstitial migration) occurs below 4$sup 0$K. Present supporting evidence includes: from both thermal neutron and fission neutron damage studies (1) a continuous, nearly structureless recovery from 4 to 43$sup 0$K independent of dose; (2) a nonlinear, decreasing damage rate at 4$sup 0$K; and (3) from 6$sup 0$K electron irradiations near threshold energy there is derived a Frenkel pair resistivity which is so small as to suggest significant loss of defects during irradiation. ... continued below

Description

Some kind of order may emerge from the numerous anomalies in the low- temperature recovery of irradiated V if it is assumed that Stage I (first recovery by interstitial migration) occurs below 4$sup 0$K. Present supporting evidence includes: from both thermal neutron and fission neutron damage studies (1) a continuous, nearly structureless recovery from 4 to 43$sup 0$K independent of dose; (2) a nonlinear, decreasing damage rate at 4$sup 0$K; and (3) from 6$sup 0$K electron irradiations near threshold energy there is derived a Frenkel pair resistivity which is so small as to suggest significant loss of defects during irradiation. The assumption of a very low-lying Stage I also helps to explain several other unusual aspects of the data, especially those relating to the sharp recovery peak at 47$sup 0$K. This is clearly a single first-order process (with a measured activation energy of 0.13 eV), but it has a strong positive dependence of population percentage upon dose, opposite to Stage II impurity detrapping peaks in several fcc metals. Also, the peak has a strong negative dependence upon irradiation temperature when equal doses put in at 4 and 31$sup 0$K are compared. (auth)
