Modification and Microalloying of Iron Carbon Alloys Using Industrial Polymer Scrapes

Abstract

The information about highly effective stimulation methods of modification and microalloying in the formation of iron-carbon alloys structure is presented. The effect of additives in minor quantities is implemented by refining effects, and by influencing the structure and composition of the liquid and solid phases, the morphology and composition of nonmetallic inclusions, intermetallides, borides, nitrides, crystallization conditions, the size and boundaries of the primary and secondary crystal grains. The developed method of finishing iron carbon alloys allows recycling carbon- containing products from organic high molecular weight polymer materials of synthetic origin, including biologically damaged, aged, and unfit for recycling materials from plastics and elastomers unsuitable for regeneration. Cheap modifying additives for cast iron were developed. The introduction of these additives significantly improves the structure and mechanical properties of alloys.
