Study of the Physical Properties of Metallic Glasses at Cryogenic Temperatures

Materials of the International Conference “Glass: Science and Practice 2017”

Abstract

The problems of using metallic glasses for fabricating magnetic cores of cryogenic and superconducting electrotechnical devices, operating at low temperatures of 77 K, are considered. The experience of creating a number of devices, including electric generators, motors and transformers with HTSC windings, is analyzed. The advantages and disadvantages of magnetic cores from annealed tapes are considered. The results of the study of losses and magnetic characteristics of domestic amorphous and nanocrystalline alloys before and after high-temperature annealing are presented.
