SELF SIMILARITY OF INCLUDING OF GRAPHITE IN CAST-IRONS
Zaporozhe national technical university
Comparative morphological analysis of graphite inclusions in ductile iron and
graphite complexes, which were separated from liquid metal during crystallization and
often precipitated in pores and cavities, was realized.
It was determined that crystals and graphite inclusions at various scale factor have
self-similarity and almost identical morphology. Graphite complexes separated from liquid
metal and compact graphite inclusions in ductile cast iron have the same form as
elementary form of graphite hexagonal lattice. Therefore formation of globular inclusions in
cast irons occurs in accordance with own hexagonal nature of graphite.
Keywords: graphite inclusions, morphology, self-similarity, hexagonal lattice, fractal
