Analysis of possible variants of the development of thermal kinetics of the interaction in the titanium — aluminum system at the dynamic change of concentration of the solvent

Abstract

Based on the synergistic approach to changing the concentration of the low-melting metal solvent in the reaction, the temperature dependence of the equilibrium concentration of the refractory component in the liquid phase near the decomposition temperature and the crystallization of the synthesized compound, a thermokinetic model of reacting in a peritectic system has been proposed. Using computer simulation the dynamics of concentration and temperature changing in a system for the case of synthesizing of the four existing intermetallics formed in the reaction system when initiating the peritectic reaction was studied. Based on the comparison of the calculated results and obtained experimental data it was determined the most probable intermetallics formed in the system.
