Modeling of Niobium and Titanium Carbides precipitates in Cluster Dynamic

The paper is focused on applying Cluster Dynamic to model the precipitation kinetics of niobium and titanium carbides. The simulation was carried on for niobium carbides in austenite and ferrite and titanium carbide in austenite. The results were compared with available experimental data and were analyzed for dependency on initial cluster distribution. The analysis showed that initial distribution does not affect the simulation after a certain point in time. It has also been shown that the case when only monomers present in very dilute alloys has significantly different behavior compare to other cases.
