1. The first question is what is your metal matrix composite? Is it powder, film, bulk? What is sizes, estimated spatial distribution of micro and nano- features.
2. With electron microscope you can see the micro and nano features directly.
3. With optical microscope you will be limited by diffraction, i.e. about half wavelength. Better results you can obtain with phase contrast microscope. Thus using the UV light, you can resolve the features of a 1-2 hundreds of nm in size.
4. In principal, there are techniques of superresolution (subdiffraction) microscopy, but they are very specific for each kind of analysed objects.
Micro features can be identified by optical microscopy. Nano features can be identified using high resolution SEM or TEM or HRTEM. It will be nearly impossible to identify both micro and nano features together in optical microscopy.
