Dear Ms. Kamde,
I worked in a project that we needed to measure powder systems with DRX.
If I understand your question, I guess you need to describe your samples structure by a quantitative way that could be perform through the Relative Texture Coefficient, RTC(hkl), which can be calculated by the comparison between the diffraction intensities [I(hkl)] of samples determined by the diffractogram lines of them and a standard, which you are comparing the samples [I0(hkl)]. The denominator of the equation is a sum of the correlation of al peaks orientation in the diffratogram. The relation is showed in the added picture. I think if you have a range of crystalline samples in powder you could try to mesure the RTC for everyone, alloy or crystal salt.
