摘要：

Tensile creep measurements on melt-spun ribbons of Pd40Ni40P19Si1, one of the most crystallization-resistant metallic glasses, were performed over a wide temperature range. The equilibrium viscosity was reached by both increasing and decreasing viscosity relaxation and was well described by a Fulcher-Vogel relation. The viscosity relaxation kinetics could not be entirely described by flow defect models. The newtonian viscous behavior of the glass near Tg was verified and a zero creep effect due to surface tension was observed.
