摘要:	The microstructural characterization of the Zr(60.0)Ti(14.7)Nb(5.3)Cu(5.6)Ni(4.4)Be(10.0) bulk-metallic-glass-matrix composites is investigated using high-energy synchrotron x-ray diffraction. The convoluted diffraction-intensity distribution in the azimuthal direction is naturally yielded from the spatial arrangements of the crystalline dendrites and their amorphous matrix. We facilitate the area selection and the intensity integration of the diffraction collected from a two-dimensional detector to characterize the diffraction intensity of the amorphous matrix. The results enable us to apply the modified Williamson-Hall plots for using the peak width to study the microstrain and micromechanism of the deformation of the crystalline phase.
