The broadening in the peaks of the XRD patterns arises due to the finite size of the crystals. If one has crystal of infinite size, the peaks in the XRD pattern
Thepeak widthobserved in x-ray scattering can be related to the grain size of the ordered structure giving rise to the scattering peak. More generally, the peak shape also encodes information about the sample order. Thus, peak shape analysis can be used to extract higher-order information. ...
Results The X-ray diffraction (XRD) patterns with only Kα1 contribution are shown in Fig. 1(a). Only (00l) peaks for the monoclinic phase can be observed, indicating good c-axis orientation. The full widths at half maximum (FWHM) in both crystals show very small values ∼ 0.05,...

We conclude that the growing of matrix distortion zones around the precipitates is well described by the 2M factors established by Houska. In terms of mechanisms, in the first stages of ageing the rapid hardening seems to not be related with the interaction of dislocations with the stress field...
