ABSTRACT:
The theoretical research of the directional solidification process of ternary systems in the presence of extended area of phase change was carried out. The mathematical model of process of a quasistationary crystallization was developed and its analytical solution taking into account the non – linear equation of the line of a liquidus was constructed. It was revealed that the deviations of the liquidus equation from the linear relation can lead to essential change of parameters of the solidification process.
KEYWORDS:
