VISCOUS FLOW BEHAVIOUR OF AMORPHOUS Pd-Cu-SiALLOY
非晶Pd—Cu—Si合金的流变行为

Strain rate and shear viscosity measurements were carried out on Pd-Cu-Si amorphous alloy with a Perkin-Elmer TSM-2 thermomechanical analyser under constant heating rate conditions. The minimum values of the shear viscosity accompanied by the glass transition and crystallization process have been observed. The heating rate dependence of the minimum values of the shear viscosity has been investigated. The viscous flow behaviour of amorphous Pd-Cu-Si alloy can be explained with the model of phase boundaries for the structural transition.
