Characterization of Mechanically Alloyed Nanocrystalline Fe(Al): Crystallite Size and Dislocation Density

Figure 4

Observed (points) and calculated (solid line) room temperature X-ray diffraction patterns of (211)_Fe and (211)_Fe(Al) peaks for (a) 12 h, (b) 14 h, and (c) 20 h (𝜆=1.7890100). Positions of the Bragg reflections are represented by vertical bars. The observed-calculated difference pattern is depicted at the bottom of each figure.
