Thermodynamic description of the Cu---Al---Mn system in the copper-rich corner

Thermodynamic description of the ternary Cu---Al---Mn system in its copper-rich corner is presented. The thermodynamic parameters of the sub-systems, Cu---Al, Cu---Mn and Al---Mn, are taken from earlier SGTE-based assessments (after modifying the Cu---Mn description slightly) and those of the ternary Cu---Al---Mn system are optimized in this study by using the experimental phase equilibrium data. The present ternary description is valid for aluminum contents up to 18 wt% and manganese contents up to 50 wt%.
