Figure 8
NBED patterns from the γ matrix of a nickel-based alloy containing ∼30% chromium obtained by SEND with a precession angle of 0.5° (see Section 5.5). For each pattern, the employed reflection lines for orientation determination with RAPID are shown in the zoomed view on the right. Despite the evident off-axis orientation of the matrix with the electron beam, the 〈001〉 zone axis was identified as the orientation for all patterns using RAPID. A detailed examination of the NBED patterns using the ASTAR system software revealed that the investigated crystal areas are tilted by (a) ∼2.6°, (b) 2.3° and (c) 1.7° from the 〈001〉 zone axis. |
