Abstract

There has been constructed a diagram of the phase composition of the Fe – C – Si – B system and developed its mathematical model. It permits to determine its phase composition by the chemical composition of the initial material. There is also solved the inverse problem, i.e. the definition of the form and quantity of the initial furnace burden components for obtaining the product of the required phase composition. The analysis established the existence in the studied four-component system of 7 individual phases. There are given examples of using the model for the assessment of the phase composition of metals.

Keywords
