Three-dimensional (3D) morphology and growth behavior of ferrite formed at
intragranular inclusions in low-carbon steel
were studied by serial sectioning and computer-aided visualization. The specimens
taken from the weld deposit were
austenitized and isothermally reacted for varying times. The length, width, and
thickness of ferrite plates were measured from
3D-reconstructed images. From the length-to-width ratio, the morphology of ferrite is
likely to be a lath rather than a plate in
this alloy. Multivariant ferrite plates
