TEMPERATURE DEPENDENCE UPON VISCOSITY OF Ni-P ALLOY ON AMORPHOUS FORMATION

The viscous flow of amorphous alloys near T_gis closely related to the viscosity of liquid alloys. On the basis of the measured surface tension and density for Ni-P binary alloys,the correla- tion between the viscosity of the melt and viscous flow process of the amorphous alloy is inves- tigated.The relationship between viscosity and temperature for Ni-P alloys going from liquid to amorphous solid may be described by the following formula:
