“…Further evidence that the irradiation-induced defect concentration is increased by dislocations is provided by the resulting changes in thermal recovery processes after irradiation with various particles. (2) However, a comparison of the damage rates and recovery of deformed fcc metals which were irradiated with electrons, deuterons, or neutrons@) indicates that no simple relation exists between the change in stage I recovery and the enhancement in damage rate. In fact, Jackson and Herschbach's general conclusion that the enhancement in damage rate can be found directly from the suppression in stage I recovery(') is not supported by the experimental evidence.…”

“…A wide range of examples are given in Refs. (I), (2), and (3). Much controversy exists as to whether the extra resistivity reflects production of more Frenkel pairs or a greater specific resistivity per Frenkel pair in the presence of large numbers of dislocations.…”

It is shown that the ratio of the resistivity increments injected by iriadiation at low temperature into deformed and into annealed specimens is related to the difference in fractional recovery that occurs in Stage I between the two specimens. Using this relation the ratio of resistivity increments to the resistivity increment due to dislocations is computed for a number of different irradiations. For a given metal and type of irradiation the enhancement of resistivity increment in a deformed specimen is closely proportional to its dislocation resistivity. It is shown that this is more in accord with explanations of the enhancement based on greater defect production per unit irradiation dose than with explanations based on greater specific resistivity of Frenkel pairs in the presence of large defect concentrations.

Pure niobium and niobium doped with 3000 to 4200 a t ppm Zr, Hf, MO, W, and Rh are irradiated a t 4.6 to 6 K in the reactor up to neut'ron doses of 2.72 x cm-2. The damage production rate of the doped samples increases in the range of 4 to 16.2 compared with the pure sample. This effect is probably due to the reduction of the radiation annealing processes caused by trapping of self interstitials a t the foreign atoms. The suppression of recovery in the doped samples up to about 45 K is also explained by tmpping reactions between the self interstitials and foreign atoms.For the doped samples new recovery substages appear in the temperature range 45 to 144 K. The isochronal recovery curves are measured up to 411 K . ReinesNiob sowie mit 3000 bis 4200 At ppm Zr, Hf, Mo, M' und R h dotiertes Niob werden bei 4,6 bis 6 K im Reaktor bis zu einer Pr'cutronendosis von 2,72 x l0ls bestrahlt. Verglichen mit der reinen Probe ist die gemessene Erhohung der Schiidigungsrate in den dotierten Proben im Bereich 4 bis l6,20/, gestiegen. Diese Erscheinung beruht wahrscheinlich auf der Abnahme von ,,radiation annealing"-Prozessen infolge von Haftung der Eigen-Zwischengitteratome an den Fremdatomen. Die Unterdriickung in der Erholung bis ca. 45 K der dotierten Proben wird ebenfalls durch Haftreaktionen zwischen den Eigen-Zwischengit,teratomen und den Fremdatomen erklart. Fur die dotierten Proben erschcinen neue Erholungsstufen im Temperaturbereich 45 bis 144 K. Die isochronen Erholungskurven xvvnrden bis zu 411 I< gemessen.
