Abstract
The dependences of the influence of the chemical composition of cast iron in the Fe-Cr-Mn-Ni system on the chromium cotent in the metal base (Cr1050о) and carbides (Cr1050Cr) after normalization from 1050 °C with aging for 4.5 hours were established. During the heat treatment of the castings, a redistribution of the elements between the phases of the cast iron occurred. The maximum chromium concentration in the base after normalization was 19.7% at 1.09% C, 3.1% Mn, 25.5% Cr and 0.19% Ni, and the minimum 2.4% at 3.91% C, 0.6% Mn, 11.43% Cr and 0.19% Ni. The maximum amount of chromium in carbides 78.4% was observed in cast iron containing 1.09% C, 5.4% Mn, 3.01% Ni and 25.57% Cr, and the minimum 43.5% at 3.59% C, 5.4% Mn, 3.01% N and11.43% Cr. The obtained dependencies allow predicting the chromium content in the metallic base and can be used during the elaboration of new compositions for wear-resistant cast iron, as well as at choice of heat treatment regimes.
