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.
