Annotation

The regularities of the crystallization process of binary amorphous alloys of the Ni-Zr system have been theoretically studied. Using the calculations carried out within the framework of the modified theory of homogeneous nucleation for binary systems, it was shown that the process of crystallization of binary amorphous alloys of the Ni-Zr system takes place in two stages. It is shown that quenching at 106 К/s allows fixing an amorphous state, and the region of amorphization of binary alloys of the Ni-Zr system is in eutectic concentration: (27-41)% at. zirconium, which is well in agreement with experimental data.
