Palukuri Nageswararao Rao

In which alloy you are trying?..

M. E. Kazasidis

I suppose that Poultons etchant is proper depending on the alloy you want to observe in the SEM.

R. Palanivel

For seeing grain boundary, you must do polishing and etch then see in the SEM analysis.

Isaac Dinaharan

Yes, absolutely, you need to etch
