Abstract

Is show that in the iron-based alloys with weight content of boron from 1,8-3,5 % and with carbon content from 2-2,5 % (w.) after crystallization the morphology of specimen includes primary dendrites of Fe3(CB) phase and plate-like eutectics γ-Fe+Fe3(CB). It is revealed that in the process of Fe-B-C alloys crystallization the formation of cubic boron carbide Fе23(CB)6 takes place as a result of preannealing at the temperature of 1173 K. The formation of Fе23(CB)6 phase occurs on peritectic dissolving of Fe2B boride, whereas eutectics Fе23(CB)6+γ-Fe is formed as a result of four-phase peritectic transformation L+Fe2B→Fе23(CB)6+γ-Fe.
