Volume 3, Issue 3, Page 226-230, Year 2012, Current Issue | DOI: 10.5185/amlett.2012.3324

Keywords: Surface concentration; bulk concentration; surface tension; geometrical factor.

Abstract: 

The concentration fluctuation in long wavelength limit (SCC(0)) has been computed from experimental data of chemical  activity of pure Al and Mn components in molten Al-Mn alloys at 1600K. The SCC(0) is used to obtain Warren-Cowely short range order parameter (α1) and ratio of mutual and intrinsic diffusion coefficients (DM/Did) for this alloy. The surface concentration of pure components with respect to corresponding bulk concentration of pure components for Al-Mn alloy at 1600K has been computed on the basis of Butler’s approach. These surface concentrations are then used to calculate the surface tension for this system. Copyright © 2012 VBRI press.
