How to locate the isomorphous MgZn2 phase existing in AA7XXX-T6 using OM/SEM/FESEM imaging ? The context of the question is - the aluminium alloy has been applied with super plastic deformation , now due to intense stirring action the precipitates sizes would have changed ... so how I can locate the n and n' phases seperately using microstructural characterization?
The growth or fragmentation of these strengthening phases in A7XXX alloy prior SPD is the focal point of this study.
