Dear Raghavendra Darji , Valentin Bogatu is in principle right; dislocation density (dd) is calculated via XRD by dd =1/D2 with D being the crystallite size D, which is calculated via the ´Scherrer equation' or Williamson-Hall expression; please see for example the answers to previous similar questions:

Hi Raghavendra Darji, I agreed with Valentin Bogatu and Gerhard Martens . The crystallite size of the sample can be determined from the broadening of the XRD peaks. Mathematically, the dislocation density (δ) can be calculated using: δ =1/D2 where D is the crystallite size. The unit is nm–2. Good luck.

I can guess that using XRD you can measure the size the crystals from the amplitude of the diffraction peaks. Monocrystals have high peaks, polycrystalline materials have low diffraction peaks. If you know the size of the crystals you can approximate the dislocation density in that sample

Dear Raghavendra Darji ,
Valentin Bogatu is in principle right;
dislocation density (dd) is calculated via XRD by dd =1/D2 with D being the crystallite size D, which is calculated via the ´Scherrer equation' or Williamson-Hall expression;
please see for example the answers to previous similar questions:
https://www.researchgate.net/post/What_is_the_best_method_to_measure_dislocation_density
https://www.researchgate.net/post/How_can_i_calculate_dislocations_density_from_the_XRD_patterns2
especially the paper given there as attachment by A. El-Denglawey (see answer #10)
By the way: D is derived from from the peak width(s), but not from the peak height(s), as mentioned above...
Best regards
G. M.
