Outline of Final Research Achievements

This work aimed at studying effects of deuterium on glissile motion of disloca-tion loops formed by irradiation-induced damages in metals.
Dynamic behavior of interstitial-type dislocation loops in Fe-9Cr-2W ferritic alloy, high purity Fe specimens etc. were studied by in-situ irradiation of 5-10 keV deuterium ions or electrons, and in-situ TEM observation. Thermal desorption spectroscopic study of irradiated deuteium was also performed using a quadrupole mass spectrometer.It was found that de-trapping of deuterium from dislocation loops and start of their glissile motion were closely correlated, and these details were studied. The obtained results suggest that deuterium atoms (or their complexes) promote nucleation of dislocation loops, and that precipitated these atoms (or complexes) on the loop dislocation suppress the precipitation of alloy elements under the irradiation and induce the thermal glide motion of the loop following the de-trapping of deuterium atoms from the loop.
