Sažetak
The Fe-Cr-Si and Fe-Cr-Al systems are the basic ones in the development of the technology for smelting a new complex alloy - aluminosilicochrome. Aluminosilicochromium can be used as a reducing agent for metallothermic production of low- and medium-carbon ferrochromium grades with subsequent use in the smelting of stainless steel grades. Construction of a diagram of the phase composition of a four-component system Fe-Si-Al-Cr, consisting of 4 three-component systems Fe-Si-Al, Fe-Cr-Si, Fe-Cr-Al, Si-Cr-Al. Three-component Fe-Si-Al system, which will be the base of the Fe-Si-Al-Cr tetrahedron. It is necessary to analyze the thermodynamic properties of compounds for binary and ternary systems.
