摘      要：Amorphous Ti–Cu–Zr–Ni alloys with minor addition of Sn and Al were prepared by melt spinning *** effects of Sn and Al additions on the microstructures and mechanical properties of glassy ribbons were *** amorphous state of ribbons was confirmed by x-ray diffraction and transmission electron microscopy,where those ribbons with Sn addition exhibited a fully amorphous *** characteristic temperature indicates that Ti45Cu35Zr10Ni5Sn5 alloy has a stronger glass-forming ability,as proven by differential scanning ***45Cu35Zr10Ni5Al5 alloy showed a better hardness of 9.23 GPa and elastic modulus of 127.15 GPa and good wear ***45Cu35Zr10Ni5Sn5 alloy displayed a pop-in event related to discrete plasticity according to *** the temperature is below 560 K,Ti45Cu35Zr10Ni5Sn5 alloy mainly exhibits *** the temperature rises between 717 K and 743 K,it shows a significant increase in elasticity but decrease in viscoelasticity after the ribbon experiences the main relaxation at 717 *** the temperature is above 743 K,the ribbon shows viscoplasticity.
