“…Neutron irradiation experiments on F-M alloys showed Cr enrichment in both a commercial and model alloy (HT9 and Fe-12CrMoVNb, respectively) [6], [7]. Meanwhile, multiple proton and ion irradiation studies reported Cr depletion in commercial HT9 and F82H, as well as in model Fe-13Cr alloys [8], [9], [10]. The most recent studies on RIS in F-M alloys were completed by Gupta, et al [11] and Lu, et al [12], both in 2006, and by Marquis, et al in 2011 [13], [14].…”

A systematic approach to measuring radiation-induced segregation (RIS) was used on four ferritic-martensitic (F-M) alloys: T91, HCM12A, HT9, and a Fe-9Cr model alloy, irradiated with 2.0 MeV protons over a range of doses (1-10 dpa) and temperatures (300-700°C). The experimental conditions are established so as to isolate the dependence of RIS on the experimental parameters: temperature, dose and bulk composition. RIS is measured at prior austenite grain boundaries (PAGBs) using the STEM-EDS technique. Chromium is found to enrich at PAGBs in all conditions with the exception being T91 irradiated to 3 dpa at 700°C. The magnitude of enrichment is small (<2 at%). Minor elements Si, Ni, and Cu also enrich consistently. A bell-shaped temperature dependence of RIS is observed in all elements. The amount of Cr enrichment decreases as a function of increasing bulk Cr concentration. Lastly, it is found that the 9Cr model alloy reaches a steady-state Cr RIS behavior at approximately 7 dpa, while the T91 reaches what may be a steady state near 3 dpa, then the amount of enrichment decreases at 10 dpa.

Depth profiles of the daniage density and the iiiicrohardness are measured in GaP single crystals implanted with 1 MeV heliuni ions. From an analysis of tlie experimental data i t follows that the rnicroliardness increases up to a darnage density of about 16% due to point defect hardening. At higher damage densities the rnicroliardness decreases rapidly, probably due to the formation of extended defects.Die Tiefenprofile der Defektdiclite und der Mikroliarte wurden fur init 1 MeV Heliumionen implantierte QaP-Einkristalle gemessen. Aus einer Analyse der experimentellen Daten folgt, dafi die Mikrohiirte bis zu einer relativen Defektdichte von etwa 16% infolge von Punktdefekthiirtung ansteigt. Bei hiiheren Defektdichten fiillt die Mikroharte steil ab, walirscheinlich infolge der Bildung ausgedehnter Defekte.
