Abstract

The Lifshitz-Wagner theory of coarsening applied to the experimental data for titanium and vanadium nitride precipitates in austenitic iron-nickel steels shows that Ostwald ripening is controlled by diffusion of the substitutional titanium or vanadium solute atoms. The influence of oxygen impurity is shown to modify both the VN coarsening behaviour and growth morphology.
