Thermodynamical analisys of Al-Cu-Mn system using RKM model Termodinamična analiza sistema Al-Cu-Mn z uporabo modela RKM

The results of thermodynamic analysis of alloys in ternary system Al-Cu-Mn are been presented in these work. Thermodynamic analysis was carried out by applying Redlich-Kister-Muggianu (RKM) method in selected sections from aluminum, copper and manganese corner, in the temperature interval from 1 073 K to 1 873 K. Thermodynamic properties (excess integral Gibbs energy and activity of components) has been calculated using Redlich-Kister parameters of constituent binary systems and presented in form of graphics. Analyzing calculated data it can be concluded that high content of manganese in alloy can significantly lower miscibility of alloy.
