Abstract
Grain boundary (GB) diffusion of 110mAg was measured in polycrystalline α-Zr in the temperature range 574 to 1024 K using microtome sectioning and γ-spectrometry to evaluate the diffusion profiles. An Arrhenius relation was determined for the GB diffusion parameter P = sδDgb, (s is the segregation coefficient, δ the GB width and Dgb the GB diffusion coefficient) with an activation enthalpy Qgb = 152±3 kJmol–1 and a pre-exponential factor
Abstract
Die Korngrenzen (KG)-Diffusion von 110mAg wurde in α-Zr im Temperaturbereich von 574 bis 1024 K gemessen. Die Diffusionsprofile wurden durch Schichtenteilung mit dem Mikrotom und der γ-Spektrometrie ermittelt. Der KG-Diffusionsparameter P = sδDgb (s = Segregationsfaktor, δ = KG-Breite, Dgb = KG-Diffusionskoeffizient) folgt einer Arrheniusbeziehung mit einer Aktivierungsenthalpie Qgb = 152 ± 3 kJmol–1 und einem präexponentiellen Faktor
The authors want to thank Dr. C. Schlesier for performing the transmission electron microscopic analysis. One of the authors, A. Ostrovsky, would like to acknowledge the support by a sholarship of the Deutscher Akademischer Austauschdienst (DAAD).
