摘要

A new theory of strain-induced precipitation of Nb(CN) in micfoalloyed austenite has been developed by considering the effect of nonequilibrium segregation of Nb on the nucleation and growth of the precipitates. With the aid of the theory, the discrepancy existing between the conventional theory for strain-induced precipitation and experimental data can be reconciled. A kinetic model has been developed based on the new theory. The model is capable of predicting both the Nb(CN) precipitation Joineries and the resulting microstructure in microalloyed austenite. Excellent agreement has been obtained between the model predictions and the experimental observations reported by different investigators.
