In this paper, we consider two alloys containing a significant part of zirconium: A1 (Zr51.32 Ti17.54 Ni15.18 Cu14.61 In1.35 ) and A2 (Ti65.23 Zr34.77 ). The samples were obtained by high-speed hardening 6 and are small thin quadrangular metal plates. The molten alloy enters the cooled drum, after which it is rapidly cooled. Due to the high cooling rate, the atoms do not have time to be distributed in an orderly manner, an amorphous structure appears. Due to the temperature gradient, the samples are heterogeneous, that is, there are two sides that differ from each other: matte (adjacent to the drum) and mirror (reverse side). In this work, only the matte side of the samples is considered, since the fastest cooling and, consequently, the solidification of the alloy occurred in this region.
Uglov et al. (Sat,) studied this question.
