A dynamic nucleation code has been developed for predicting the evolution of vacancy clusters and nanometer-size voids in rapidly-quenched metals containing helium and oxygen impurities. Calculations have been carried out for typical quench rates and subsequent heat treatments of the powders during and after consolidation. These calculations show that high densities of submicroscopic voids can form in rapidly quenched metal powders, due to the quenched-in vacancy supersaturation and the entrapment of gases. The significance of these nanometer voids to the morphology or precipitates formed in rapidly-solidified steels is discussed.
