摘要：

In this paper the ″region boundary″ model is suggested on the basis of the study of the viscous flow of Ni-P, Fe-Si-B amorphous alloys under compression and tension. The flow coefficient determined from the experiments is about 0.3-0.5 which is almost consistent with the value estimated from the model. In order to obtain the ideal glass transformation temperature Tg, a temperature Tvs is defined at which stable flow starts. The tests were performed with TMS-2 and DSC-2 thermal analysers. The obtained viscosity may be extended to the liquid state.
