Abstract:

The nucleation and growth kinetics of helium bubbles upon post-radiation annealing was investigated on irradiated beryllium specimens by the small-angle neutron scattering technique. According to the experimental findings, the increase in the annealing temperature from 650 to 1100°C was accompanied by the increase in the effective bubble radius from about 40 to 120 Å. At the same time, the relative aggregate volume occupied by bubbles increased from about 7 × 10-5 to 2 × 10-3 and the aggregate specific surface area, from about 7 × 102 to 6.9 × 103 cm-1. The bubble-size distribution function was determined. It was found that gas bubbles nucleated and grew in the temperature range 650-1100°C at an almost constant rate.
