Abstract (English):
The evolution influence of the graphite form (from a platetype form to a globular one) upon structural cast iron properties was analyzed and grounded, there were also considered cast iron peculiarities and prospects of their commercial application is estimated. For castings production the expediency of rational application of unregulated graphitized cast iron with the intermediate transitional morphology of graphite inclusions instead of grey iron high grades with lamellar graphite (GI 30, GI 35) and malleable cast iron is shown. The appropriate use substantiation of mentioned cast iron types taking into account their peculi-arities is shown.
