Abstract
The development of advanced technologies includes the development of new materials, which include composite amorphous nanocrystalline materials characterized by a unique combination of magnetic and mechanical properties (the latter include high strength, hardness, and wear resistance and others). However, the potential for using such materials is limited, since they are relatively quickly embrittled (lose their plasticity) even at room temperature. The properties of plasticity cannot be restored by heat treatment of the amorphous phase. It is found that properties of plasticity can be restored using thermal cycling in the interval between the temperature of liquid nitrogen (77 K) and room temperature (295 K). This process of treatment is called rejuvenation; it turns out to be acceptable only for bulk samples obtained in the form of rods. It is not suitable for samples in the form of ribbons with a thickness of 20–50 μm (the vast majority of amorphous alloys are obtained in this form). A modernized technology for treating such samples of amorphous alloys and partially crystalline alloys using cryogenic thermocycling is presented. This technology allows one to restore the amorphous structure and plasticity of thin ribbons. X-ray diffraction patterns of ribbon samples of alloy Al87Ni8Gd5 pre-annealed at a temperature of 170°C with the fraction of the nanocrystalline phase not exceeding 10% before and after several successive cooling/heating cycles show that the amorphous structure of the initial sample can be completely restored by increasing the number of cycles to two hundred.
