Abstract  The volume effect of 6 PdSi-base amorphous alloys on heating has been measured by a tension method. The fractional free volume of 3 ternary alloys at the glass transition temperature is calculated to be 0.02—0.03 which is approaching the value 0.025 of ordinary amorphous materials. The relationship between free volume increment of 6 materials in equilibrium state and relative viscosity is consistent with the viscous flow free volume model.
