Dear Edson Samaniego,
The info below should be helpful:
How can i determine crystal size and crystallinity in x-ray diffraction pattern?

Yes. By Scherrer equation, that provides crystallite sizes. The Williamson Hall plot could instead provide both size and strain contributions
First, search here or internet for how to do it, since this has been extensively discussed. Then if you have questions how to apply the specific techniques, ask here for clarification.
It's fair to say, "already asked and answered."
if you have a diffraction pattern of the tem is possible ? because I understand that it is easy from the DRX but I seek to know if from a diffraction of tem it is possible. I already know the interplanar distance d and hkl
Edson Samaniego , kindly refer to the XRD section of following articles to calculate the crystallite size:
