Dear researchers,
You are invited to this discussion, for shedding light into the very basic fundamental principles involved in a typical XRD analysis, in particular, metal matrix composites.
I'd like to recommend the following articles:

Dear Ebenezer Jacob Dhas D.S.
It looks simple, however, it is not an easy task.
MMC's suffer from high orientation in many cases, primarily due to the synthetic pathway and the initial characteristics of the starting materials.
In principle, for MMC's, the XRD would give you a possibility, as metals, to explore at deep the ion diffusing and interlayers diffusing effect in the system properties. Once again, it depends on the quality of the starting materials.
They demand a rotating sample holder for precision on relative intensities to prevent at maximum the preferred orientation. Even a razing angle experiment will help the understanding of the system.
If you can not get a representative amount of the material in fine powder with a straight control of particle size, your results may only be qualitative, and that is the main difficulty in such study.
Inhomogeneity may play a significant role, start with an SEM and EDS distribution map is a good idea, may prevent a lot of work to be repeated. The interface layers have a significant effect on the mechanical properties of the composites, therefore, need to be correctly explored.
In general, several exploratory experiments are necessary before the definition of a useful setup, that brings you meaningful results.
There is significant care to be taken, to have meaningful results. In the literature, you may find a description of MMC's with no physical meaning, the result of neglecting the difficulties listed above.
Best regards,
WNM
