Structure formation in materials based on Fe-C-Si and Fe-C-Al systems (cast irons) prepared from dispersed mechanical engineering waste

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. The paper presents fn alternative technological process for producing compact forms of graphite inclusions in the materials based on the Fe-C-Si and Fe-C-Al (cast iron) systems. It differs from traditional methods of obtaining compact forms of graphite inclusions, which consist in modifying the molten iron or annealing white iron: The proposed technological process is based on a synergistic complex of foundry-metallurgical factors affecting the cast iron in the stages of its melt preparation and crystallization in a mold.
