英文摘要	The structure and properties of amorphous alloys undergo significant changes under extreme conditions, and the deformation mechanism is not uniform. This paper reviews the changes in the microscopic morphology and mechanical properties of bulk amorphous alloys at extreme cryogenic conditions to clarify the thermal effects on the mechanical properties of amorphous alloys. It mainly elaborates the influence of cryogenic temperature on tensile and compressive mechanical properties for bulk amorphous alloys and lists the excellent mechanical properties of bulk amorphous alloys at cryogenic temperatures, such as a high yield strength of 2 217 MPa. In addition, the electrical and magnetic properties of bulk amorphous alloys under different cryogenic temperature conditions are also reviewed, and it is found that bulk amorphous alloys also have outstanding performance in magnetic refrigeration. For example, the transition temperatures from ferromagnetic to paramagnetic for Co45Er55 and Co35Er65 are 26 K and 15 K, respectively. The change in magnetic entropy is determined according to the thermodynamic Maxwell relationship. With an increase in Er concentration, the magnetic entropy change value also decreases. Under a magnetic field of 5 T, the magnetic entropy change peaks of Co45Er55and Co35Er65 are about 10.8 J·kg-1 ·K-1 and 9.8 J·kg-1 ·K-1, respectively, indicating that the Co35 Er65 alloy is more likely to be a candidate for magnetic refrigeration. The discussion in this paper is of great significance in further understanding the relationship between microscopic morphology and mechanical properties of amorphous alloys at cryogenic temperatures, and provides a theoretical basis for the application of bulk amorphous alloys under extreme cryogenic temperature conditions, which shows important theoretical and practical significance for engineering applications of bulk amorphous alloys as new materials as well. © 2022 Cailiao Daobaoshe/ Materials Review.
