摘要：

Theoretical bases for calculation of metastable phase transformations with participation of supercooled melts, such as immiscibility and glass formation, are considered. A dataset of the model parameters for the thermodynamic properties of phases in the Cu-Fe-(Ti, Zr, Hf) systems is presented for performing corresponding calculations in the framework of the CALPHAD method. The diagrams of metastable phase transformations with participation of supercooled liquid alloys and terminal solid solutions are calculated. The composition regions of metastable immiscibility of supercooled ternary liquid alloys are presented. The composition regions for producing rapidly quenched amorphous Cu-Fe-(Ti, Zr, Hf) alloys are theoretically estimated. The production of ternary immiscible rapidly quenched amorphous alloys in the composition region with x(Me) approximate to 0.1-0.2 is predicted. Bulk amorphous alloys are expected to be produced in the composition region with x(Me) approximate to 0.3-0.6.
