Spherulitic formation in cast iron with spherulitic graphite, polished.
Specimen preparation and image interpretation:
Dr. H.-L. Steyer, Kesselsdorf. Germany.
Polarization with additional lambda plate, sub-parallel:
This technique enables optimal contrasting of the structure in the interior of the spherulite section. The interference colors make it possible to see even more details than with simply crossed polars. |
