Abstract
In this paper we study the structural changes in the cast iron associated with an increase in the
copper content up to 14.7 wt. %. The results of the study of copper-containing particles of various
sizes by optical microscopy and by scanning and transmission electron microscopy submitted in
paper. In the course of the work carried out analysis of the shape, size and composition of the
particles, their classification, as well as the scheme of allocation of copper-based particles in the
structure of cast iron. Four types of copper-based inclusions found. These inclusions are allocate in
a wide range of sizes from 20 nm to 240 microns. The paper describes the conditions of formation
and the differences between all four types of particles.
