Abstract
SINCE the discovery of voids in neutron-irradiated stainless steels by Cawthorne and Fulton1 considerable effort has been made to obtain experimental data on the nucleation and growth of voids and to understand the processes involved. The phenomenon has been of interest to the designers of fast reactors and could also be an important factor in material development for fusion reactor requirements. From both experiment and theory it is generally expected that for irradiations in constant temperature conditions, the voids will grow and the total void swelling increase with increasing displacement damage. Results are presented here which are contrary to this behaviour and show that in molybdenum and its alloy TZM (Mo, 0.5% Ti, 0.1% Zr), conditions exist where voids initially grow but then shrink as the irradiation proceeds.
