摘要：

In this paper, Cu52Zr37Ti8In3 bulk metallic glass has been studied by nanoindentation. Three different ways for nanoindentation tests were employed. Load-control nanoindentation was used to investigate the effect of the loading rate on the hardness and Young's modulus. Young's modulus of the specimen shows a loading rate dependence. The constant-load indentation creep measurement was performed. The creep data were fitted with the generalized Kelvin model, and the compliance spectrum and retardation spectrum were derived. Furthermore, the storage compliance and loss compliance were also discussed. For characterizing the change of the hardness and Young's modulus with increasing indentation depth, depth-control nanoindentation analysis was conducted. The results show that both the hardness and Young's modulus decrease with nanoindentation depth.
