摘要The viscosity of liquid AL(86-x)Cu(10+x)Ce(4) (x = 0-3) alloys has been measured by an oscillating crucible method in the temperature range from melting temperature (T-m) up to about 1500 K. Viscosity and activation energy decrease with increasing Cu content in Al-CuCe alloys. Activation energy of Al86-xCu10+xCe4 (x = 0-3) alloys was estimated to be 1467.1, 1244.8, 1235.2, 1140.6 cat mol(-1) for Al86-xCu10+xCe4 (x = 0-3) alloys. The temperature dependence of the viscosity is discussed in the framework of free volume model as well as Arrhenius model for viscous flow. Fitted parameters To by Vogel-Tammann-Fulcher (VTF) equations are 314.66, 306.9, 290.52, 276.24 for Al86-xCu10+xCe4 (x = 0-3) alloys and can be used to determine the glass-forming ability. The free volume changes with temperature in the liquids were calculated. (C) 2003 Elsevier B.V. All rights reserved.
