XRD results also showed that the amount of β-phase grains in the matrix increased faster than growth rate of the whisker grains at the early stage of sintering. The intensities of the peaks diffracted from the whisker grains increased faster than those diffracted from the matrix β-phase ...

a, XRD patterns of the control, MA, PEA, t-BA films deposited on silicon substrates. The asterisk symbols denote the peaks of silicon. The perovskite reflections in the XRD pattern from the MA film are shifted to lower angles suggesting some MA+ incorporation into the A-site of the 3D pe...
Figure 1: (a) Symmetric 2θ-ω XRD scans and (b) FWHM values of XRCs for GaN 002 and GaN 102 diffraction peaks. The full-width at half-maximum (FWHM) of the 002 peak is sensitive to the presence of screw and mixed dislocations, while the 102 scans give information on edge dislocati...
In this study, aluminum AlMgSi0.5 (EN AW-6060) was coated onto silicon nitride Si3N4 ceramic substrates using friction surfacing technology. Experimental work revealed that the harmful effects of thermal shock (e.g., substrate cracking, coating delamination) observed with other material combinations ...
Further analysis of the crystalline phases by XRD enables the calculation of the amount of free silicon. The proposed complex method allows the characterization of such complicated processes as silicon nitride decomposition, microstructure formation and, in particular, the formation of the nanoscale grain...
are presented in Fig.4a. The corresponding analysis of the patterns is provided in Table2. This figure confirms the presence of XRD peaks associated with both porous silicon and crystalline silicon, which indicates the successful formation of porous silicon. The peaks corresponding to porous silicon...
