Abstract: The method of using an image
analyser to display the growth kinetics of ferrite is proposed.
The problem of three-dimensional growth is converted to
two-dimensional, and the growth kinetics of ferrite is displayed
on plane. Comparing the image of growth kinetics of ferrite with
the true microstructure it is shown that the structure,
morphology, distribution, size, colour and grey level are quite
similar for both cases. The two-dimensional curve of growth
kinetics of ferrite obtained by image analyser is corrected by
three-dimensional curve from calculation using statistical mean
radius of graphite spheres to make the two-dimensional image of
growth kinetics of ferrite being in quantitative agreement with
true process of three-dimensional growth kinetics of ferrite.
