Untersuchung atomarer Fehlstellen in verformtem Kupfer mit Hilfe des elektrischen Widerstandes

Das Erholungsverhalten des elektrischen Widerstandes von plastisch verformtem Kupfer (Reinheitsgrade: 99,99%, 99,999%) wird im Temperaturgebiet zwischen -40 und 250 °C untersucht. In diesem Temperaturgebiet werden drei Erholungsprozesse beobachtet. Die erste Erholungsstufe (Stufe III, Aktivierungsenergie (0,64 ± 0,04) eV) wird auf die Rekombination von Zwischengitteratomen mit den (beim Verformen in etwa gleicher Konzentration entstandenen) Leerstellen zuruckgefuhrt. Die daran anschliesende Stufe IV (Aktivierungsenergie (1,05 ± 0,05) eV) wird, auf Grund der Ubereinstimmung ihrer Aktivierungsenergie mit der nach Abschrecken in diesem Temperaturgebiet gefundenen, dem Ausheilen einzelner Leerstellen zugeschrieben. Bei der dritten der beobachteten Erholungsstufen handelt es sich um die wohlbekannte Stufe V. The recovery of the electrical resistance of cold rolled copper (purity 99.99% and 99.999%) was studied in the temperature range −40 to 250 °C. Three recovery processes were observed in this temperature range. The first recovery stage (stage III, activation energy (0.64 ± 0.04) eV) is attributed to the recombination of interstitial atoms with vacancies (produced in nearly equal concentration during deformation). The subsequent stage IV (activation energy (1.05 ± 0.05) eV) is ascribed to the annealing of single vacancies, since the measured activation energy agrees with that obtained in the same temperature range after quenching. The third of the observed recovery stages is the well-known stage V.
