Abstract:
Crystallographic aspects related to the formation of duplex AlN–Nb(C,N) precipitates in 0.2% C steel have been evaluated by transmission electron microscopy. Nb(C,N) precipitation occurs with a compromise orientation relationship on favorably oriented AlN particles in the microstructure to minimize the barrier to Nb(C,N) nucleation and growth.
