英文摘要	The effects of annealing and cryogenic thermal cycles on the structure and properties of Zr-based bulk amorphous alloys were studied by X-ray diffraction (XRD) and differential scanning calorimeter (DSC), universal mechanical testing machine, scanning electron microscope (SEM) and electrochemical workstation. The results show that the structures of samples after annealed at glass transition temperature (Tg) and below Tg are all amorphous. With the increase of annealing time, the thermal stability of the alloy decreases, the corrosion resistance gradually increases, and the mechanical properties increase first and then decrease. The plastic strain Εp reaches 16.44% at 500 K (0.6Tg) for 30 min. The annealed alloy (0.6Tg, holding for 30 min) is still amorphous after cryogenic cycle treatment. With the increase of cycle times, the thermal stability, corrosion resistance and mechanical properties of the alloy samples are improved gradually. The plastic strain Εp reaches 19.05% after 90 cycles. Generally speaking, proper annealing process and cryogenic cycle treatment conditions can be used as effective methods to improve the properties of the alloy. © 2021, China Science Publishing & Media Ltd.
