Abstract
The probability of solidifying titanium carbide from iron–carbon melts is estimated thermodynamically. The Gibbs energy of the corresponding chemical reaction is chosen as a solidification criterion. The effect of the melt composition and temperature on the formation of titanium carbide particles is determined. Alloying of castings of alloys based on the iron-group metals with titanium carbide, which forms in a melt as a result of self-propagating high-temperature synthesis between master alloy components (titanium, black carbon), enables one to form dispersed 4–8-μm TiC particles, which increases the microhardness of the materials by 20–30%.
