Effects of defect trapping and radiation-induced solute segregation on void swelling

OSTI ID:7285999
The effects of defect trapping and radiation-induced segregation on void swelling are discussed. It is shown that the effects of trapping of interstitials and/or vacancies on swelling can be described by a modified, temperature dependent recombination rate constant in the usual coupled reaction rate equations describing swelling without trapping effects. Swelling is reduced by either vacancy or interstitial trapping; however, the interstitial-solute binding energy must exceed the difference in the motion energy of vacancies and that of interstitials to be effective. Shifts in peak swelling temperature are small; in the case of vacancy trapping this is a consequence of high steady-state and thermal vacancy-solute complex concentrations at low and at high temperatures, respectively.
