Secondary electron vs back scattered in SEM, like inspection of microstructure of metals in more details.
This question is discussed in every SEM student book.
In general, SE provides surface topography - quasi-3D pictures, BSE provides information about surface heterogeneity. BSE is more suitable for metals microstructure. Modern microscopes can operate in both modes simultaneously with adjusted rate SE/BSE signal.

We have used SE mode to determine the surface morphology of our samples (Ceramics/Ferrites) while BSE was used to identify the secondary phases and sometimes magnetic precipitates and boundaries in our sample.
