Реферат:	eng: The methods of directed crystallization and thermal analysis were used to construct the section Cu0.19Fe0.33S0.48–Cu0.31Fe0.23S0.46 of the liquid–solid diagram of the Cu–Fe–S system. Pyrrhotite solid solution (Fe, Cu)S1±δ (Poss) and nonstoichiometric isocubanite Cu1.1Fe2.0S3.0 (Icb*) form from melt (L) successively. Isocubanite forms at 970 °C by peritectic reaction L + Poss → Icb*. At 930 °C, peritectic reaction L + Icb* → Iss proceeds with formation of intermediate solid solution with average composition Cu1.0Fe1.2S2.0 (Iss). On the basis of the results from this paper and earlier published works, we built a fragment of liquidus surface for the Cu–Fe–S system in the crystallization field of nonstoichiometric isocubanite and stoichiometric isocubanite CuFe2S3 (Icb). © 2017, Akadémiai Kiadó, Budapest, Hungary.
