Abstract

The void swelling behavior of molybdenum bombarded with 3.1. MeV 51V+ ions over a temperature range of 750 to 1500°C and a dose range of 2 to 50 displacements per atom (dpa) is reported. The results are analyzed using present void nucleation and growth theories, and are compared to previous ion and neutron irradiation results for molybdenum. This study presents strong evidence that void swelling in molybdenum is controlled by formation of void superlattices at irradiation temperatures up to 1100°C and by an equilibrium void spacing based on defect diffusivities above that temperature. Differences in dose rates seem to have a role in determining the temperatures at which swelling is found, but not in determining the actual swelling behavior.
