ABSTRACT Time-dependent deformation processes during nanoindentation have been investigated on a Pd 40 Cu 30 Ni 10 P 20 bulk metallic glass. Deformation under constant load has been studied as a function of prior loading rate and temperature. The constant-load displacement of the indenter into the sample shows classic relaxation kinetics and reveals the importance of anelasticity for the mechanical behavior of metallic glasses at the nanoscale.

    ABSTRACT: Creep strain recovery and structural relaxation of the amorphous metallic glass Fe40Ni41B19 after longtime loading at different annealing temperatures below the glass transition temperature have been studied using anisothermal differential scanning calorimetry (DSC) and dilatometry (TMA). It has been demonstrated that structural relaxation effects depend on the stress-annealing temperature of the amorphous ribbon. The structural relaxation states of the amorphous ribbon annealed at different temperatures under and without applied stress have been compared. The activation energy spectra were calculated from the anisothermal dilatometric measurements using the modern method based on the Fourier transformation technique. The influence of the annealing temperature on the shape of creep strain recovery spectra has been analyzed.

    ABSTRACT: In this work, the time-dependent plastic deformation behavior of Ti 40 Zr 25 Ni 3 Cu 12 Be 20 bulk and ribbon metallic glass alloys was investigated using a nanoindentation technique at room temperature with the applied load ranging from 5 to 100 mN. The stress exponent n, defined as e_ ¼ As n , has been derived as a measure of the creep resistance. It was found that the measured stress exponent increases rapidly with increasing indentation size, exhibiting a positive size effect. The size effect on the stress exponent n obtained from the bulk sample is more pronounced than that obtained from the ribbon sample. The deformation mechanism involved will be discussed.

    ABSTRACT: In this article, a simple mean-field model is developed for quantitatively understanding the anelastic deformation in metallic-glasses (MGs). By relating the anelastic strain of an MG under a constant stress to the constrained configurational transition of liquid-like phases, we are able to derive the dynamic equation that captures the essential features of anelastic deformation hitherto reported. The important implications of this mean-field model are also discussed with reference to the recent findings of nano-scale structural heterogeneity in MGs.
