Phase transformation and microstructure study of the as-cast Cu-rich Cu-Al-Mn ternary alloys
Four Cu-rich alloys from the ternary Cu-Al-Mn system were prepared in the electric-arc furnace and casted in cylindrical moulds with dimensions: f=8 mm and length 12 mm. Microstructural investigations of the prepared samples were performed by using optical microscopy (OM) and scanning elect...

| Summary: | Four Cu-rich alloys from the ternary Cu-Al-Mn system were prepared in the
electric-arc furnace and casted in cylindrical moulds with dimensions: f=8 mm
and length 12 mm. Microstructural investigations of the prepared samples were
performed by using optical microscopy (OM) and scanning electron microscopy,
equipped by energy dispersive spectroscopy (SEM-EDS). Assignation of
crystalline phases was confirmed by XRD analysis. Phase transition
temperatures were determined using simultaneous thermal analyzer STA DSC/TG.
Phase equilibria calculation of the ternary Cu-Al-Mn system was performed
using optimized thermodynamic parameters from literature. Microstructure and
phase transitions of the prepared as-cast alloys were investigated and
experimental results were compared with the results of thermodynamic
calculations. |
