Figure 4
Lattice-parameter change of the nitrided ferrite matrix upon precipitation of α′′ as a function of the fraction of N precipitated for a specimen of ferrite containing 0.24 at.% N. Calculations on the basis of equation (4) (solid line) and equation (1) (dashed line), considering the effect of nitrogen depletion of the ferrite matrix. The change of the ferrite lattice parameter due to only N depletion is also shown [dotted line; calculated using equation (1) of Mittemeijer et al. (1980)]. |
