| Abstract: |
In situ transmission electron microscopy investigations were carried out on a supersaturated nitrogen ferrite to characterise the precipitation kinetics of alpha `'-Fe16N2 nitrides at 85 degrees C. The coarsening behaviour consists of two stages. The first stage obeys the LSW theory and the coarsening rate was determined as 11.2 nm(3) s(-1). The second stage corresponds to the stabilization of coarsening, and was assumed to be related to the coherency loss between the precipitates and the matrix. (c) 2010 Acta Materialia Inc.
