Description
Summary:In the later stages of decomposition of a supersaturated solid solution, an important role is played by the dissolution of grains of new phase dispersed throughout the solution (coalescence). In the present work the kinetics of this process is investigated for swelling, where the grains of new phase are bubbles containing inert gas. There are two cases to be considered, (1) post-irradiation annealing where the total quantity of gas in the system is constant and (2) the total quantity of gas in the system increases with time, as in irradiation at elevated temperatures. An asymptotic solution to this problem has been obtained. The ultimate number of bubbles and their mean dimensions have been derived and the ultimate increase of volume calculated.
