Abstract
In this paper, indentation creep of two Cu-Zr-Ti-In bulk metallic glasses has been investigated via nanoindentation tests. The displacement–time curves of the creep processes are described with the generalized Kelvin model. The creep displacement, stress exponent, compliance spectrum and retardation spectrum for different specimens are discussed comparatively. Moreover, the effect of the employed exponential terms on relaxation peaks is also interpreted. The values of J0 in the present work approximately equal to the reported values of bulk metallic glasses. The retardation spectra indicate that Cu58Zr34Ti5In3 has a more relaxed state.
