Microstructure and grain refining performance of Ce on A380 alloy
Vončina M., Mrvar P., Petrič M., Medved J.
In the present work, the microstructure and grain refining performance of Ce
on A380 alloy have been investigated, using thermal analysis, light
microscopy with polarized light and scanning electron microscopy (SEM). The
purpose was to study the influence of Ce addition on the formation of the
microstructure. Ce changed the morphology of eutectic Al2Cu phase and caused
small formation of primary crystals of αAl. Furthermore Ce phase was detected
indicating quaternary phase AlCeCuSi (Al9Ce2Cu5Si3).
