英文摘要	In the cryogenic temperature environment, the movable parts of traditional crystalline components or equipment will be stuck and cracked, and characteristic change and even brittle fracture will occur. The influence of cryogenic extreme environment such as temperature mutation and high strain rate shocks on metallic glass severely restricts its application in industry. Due to special properties of higher strength and better plasticity at cryogenic temperature, bulk metallic glass has great application advantages in extreme conditions such as polar scientific research and aerospace. A (Zr0.6336Cu0.1452Ni0.1012Al0.12)(97)Tm-3 bulk metallic glass was chosen in this paper, and the effect of cold-heat treatment time on the microstructure, mechanical properties and electrochemical corrosion resistance were studied. It is found that when the treatment time is set from 30 min to 90 min, the crystallization volume fraction of specimens increases from 2.3% to 4.0%, and the compressive strength increases from 1703 MPa to 1805 MPa. The smaller self-corrosion current density and larger electrochemical impedance in 3.5 wt% NaCl solution indicate that the bulk metallic glass has excellent corrosion resistance after cold-heat treatment. This study provides a strong theory support for the application of bulk metallic glasses in cryogenic temperature extreme environment fields.
