Figure 5
Oriented selected-area electron diffraction pattern recorded from a FIB cross section sample of aluminium alloy AlSi1MgMn in a JEOL JEM-F200 at 200 kV. The uncalibrated diffraction pattern was analyzed in the same manner as the diffraction pattern shown in Fig. 3. The determined distances of the reflections from the center are 235 pixels (A), 239 pixels (B) and 275 pixels (C). The thereby calculated ratios are
rB/rA = 1.02 and
rC/rA = 1.17. The measured angles are ∠A–B = 70.6° and ∠A–C = 55.2°. |
