英文摘要	The effect of loading rate and holding time on the creep deformation behavior of (Zr0.6336Cu0.1452Ni0.1012Al0.12)97.4Er2.6 bulk metallic glass (BMG) was investigated by nanoindentation technique. Results demonstrate that the creep displacement of the specimen increases with the increase of loading rate or holding time. On the other hand, the hardness (H) of specimen falls with the rise of loading rate or holding time. The H drops with the growth of indentation depth during the nanoindentation process, which indicates that the specimen has a size effect. The specimen shows a serrated flow phenomenon which has rate dependence. Specifically, as the loading rate declines, the serrated flow phenomenon becomes more obvious. The creep stress exponent of the specimen goes down with the increases of loading rate or holding time. Copyright © 2020, Northwest Institute for Nonferrous Metal Research.
