Abstract

The results of the thermodynamic estimate of probability of titanium carbide crystallization from iron-carbon melts is proposed in paper. The Gibbs energy of the corresponding chemical reaction was chosen as a crystallization criterion. The influence of the melt composition and its temperature on the process of formation of titanium carbide particles is determined. The alloying of castings from alloys based on iron group metals with titanium carbide, which is formed in the melt due to the reaction of self-propagating high-temperature synthesis (SHS) between the components of ligature (titanium and carbon black), makes it possible to obtain dispersed TiC particles with the size of 4 – 8 μm, which leads to an increase in the materials hardness by 20 – 30 %.
