I have added 5 wt. % Ni to an Al-Zn-Mg-Cu alloy and it has resulted in finer Al-Mg-Zn2 eutectic structure. It did not effect eutectic morphology, only eutectic spacing were reduced. Any thoughts?
Note that EDS only does element measurement and XRD is not quite accurate for phase concentration measurement
