Mathematical model of the diagram of the Fe-Si-B composition system

Mathematical model of the diagram of the Fe-Si-B composition system

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...

Zusammenfassung: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.
