Abstract

A diagram of the phase composition of the Fe – Si – B system is constructed in the form of elementary triangles of coexisting phases and its mathematical model was created. Its isothermal sections are given in the temperature range of 300 - 2 000 K. The diagram is composed of one-component phases Fe, Si, B, binary compounds Fe₃Si, Fe₂Si, Fe₅Si₃, FeSi, FeSi₂, FeB, Fe₂B, SiB₄, SiB₆, SiB₁₄, as well as ternary phases Fe₅SiB₂ and Fe₅Si₂B. To estimate the sizes of crystallization fields, the areas of elementary triangles were calculated, the probability of existence (prevalence) of each compound in the phase space of the diagram was established.
