Description
Yield stress measurements have been performed on irradiated and annealed-irradiated high purity (5 wt ppm interstitials) and intermediate purity (27 wt ppm interstitials) molybdenum single crystals of (100), (110), and (491) orientations. Radiation anneal hardening which is the additional increment in yield stress over that observed in irradiated samples was observed for all orientations. Radiation anneal hardening was smaller in samples with the higher impurity interstitial concentration. The proposed mechanism, therefore, for the observed anneal hardening is the migration of self interstitials to the radiation produced defect clusters. An bestrahlten und bestrahlten-getemperten, hochreinen (5 Gew.ppm Zwischengitterplätze) Molybdäneinkristallen und Molybdäneinkristallen mittlerer Reinheit (27 Gew.ppm Zwischengitterplätze) mit (100)-, (110)- und (491)-Orientierung wurden Streckgrenzenmessungen durchgeführt. Bestrahlungsausheilhärtung, die den zusätzlichen Zuwachs der Streckgrenze über die in bestrahlten Proben beobachtete darstellt, wurde für alle Orientierungen beobachtet. Die Bestrahlungsausheilhärtung war in Proben mit höherer Stör-stellenzwischengitterkonzentration geringer. Der vorgeschlagene Mechanismus für die beobachtete Ausheilhärtung ist deshalb die Wanderung der Eigenzwischengitterfehler zu den bestrahlungsinduzierten Störstellenagglomeraten.
