Abstract This work is a systematic study of the creep behavior of metallic glasses, α-Pd_(80)Si_(20) and Cu_(60)Zr_(40).In particular,we studied the influence of stress,temper- ature and pre-annealing treatments on creep curves.Quantitative relations be- tween viscosity and the pro-annealing parameters(t_a and T_a)were obtained as following: η=K_1+K_2 ln t_a and η=C exp(T_a/α) Results were also obtained for“Changing-Load Creep”and“Secon-drun Creep” measurements.
