Diffusion of Ce-Al Melts Measured by Sliding Cell Technique

Abstract:

The diffusion behavior of Ce-Al alloy melt at three temperatures of 943K, 953K and 963K was investigated by sliding shear method. The inter-diffusion constants D show Arrhenius-type temperature dependence in the investigated regimes. Compared with the previous results achieved in Ce-Cu melt, liquid Ce-Al displays a much slower diffusion behavior and rather higher activation energy E_D, which was caused by the strong interaction between Ce and Al.
