Resistivity Studies of Electron Irradiated Iron

Abstract: Isochronal annealing studies of 1,3 MeV electron irradiated iron have been performed. Results indicate long range interstitial migration occurs in resistivity annealing substage IE (120 to 150 OK).Eisenproben, die mit 1,3 MeV-Elektronen bestrahlt worden waren, wurden isochron getempert. Die Resultate zeigen, daB im Teilbereich I E (120 bis 150 OK) des Ausheilens der elektrischen Widerstandserhohung Zwischengitteratome uber weite Entfernungen wandern.The purpose of this work was an investigation of point defect… Show more

“…Thus, Moser [44], following n-irradiation found considerable structure in the 200 K relaxation, which he classified into two subgroups II A and II B , situated at 183 and 233 K. His analysis yielded activation enthalpies for reorientation of 0.55 and 0.70 eV, respectively. Both subgroups were found to recover concomittantly in a first stage from 200 to 280 K, followed by a second stage from 350 to 400 K. Following RRR measurements the recovery at 200 K, on the other hand, was tentatively interpreted as Stage II C [119,120]. Blythe and Kronmu È ller [121 to 123] also detected two groups of reorientation-type relaxation processes in the temperature range from 200 to 300 K following n-irradiation.…”

“…)+dz), and to formulate the function of the spatial variation of the barrier heights with respect to the saddle points of "migrating" vacancies. According to [lo] we represent the barrier dist,ribution function in the following form : @!/+LIZ = E,,F(rZ,l+A, -r,) 3 Here r , 6, e, are the saddle point spherical coordinates with respect to the dumbbell, fixed a t the site 0.
