Figure 3
Processing the SAED pattern of an austenitic chrome–nickel–molybdenum steel in (a) with the program RAPID (Weirich, 2024a  ,b) led to the six indexing results shown in Fig. 1. The graphical outputs shown in (b) to (f) were obtained by using the last entry in the list with the RAPIDviewer program. As shown in (b), (c) and (d), the RAPIDviewer program allows one to index the diffraction spots either with hkl Laue indices or, if the lattice parameter of the cubic unit cell is known, with their corresponding d(hkl) values. For the latter, the `filled spots' option was unchecked and `scale factor spots' was set to 4. The figure in (e) shows the pseudo-3D representation for a primitive cubic unit cell in crystal space that has been determined by the program from the indexed [112] SAED pattern. Herein the red, green and blue lines refer to the cubic unit cell's axes, a′, a′′ and a′′′, in that order, and the cyan point at the unit cell's edge marks its origin. The IPF plot in (f) shows a marker for the [112] zone-axis direction within the standard stereographic triangle of the cubic system according to the common conventions (He, 2024). |
