Figure 4
(a) Orientation mapping according to the inverse pole figure of the surface normal on a cross section of the arc-melted button (see insets; centre of the IPF of FeAl2 corresponds to [001]FeAl2Chumak, standard triangle of FeAl encloses ![[[100]_{\rm FeAl}}]](teximages/kc5028fi74.gif) , [110]FeAl and [111]FeAl). Blue lines indicate minima and maxima of the lamella trace rotation with respect to the horizontal edge of the colony in the centre of the image. (b) An example of a SEM micrograph on a cross section prepared by FIB (secondary electron contrast, tilt-corrected). The blue dashed line indicates the mean of the lamella trace inclination with respect to the sample surface obtained from several cross sections. The standard deviation is highlighted by dotted lines. (c) Stereographic projection of the determined orientations of the colony in the centre of (a). Blue lines indicate rotation and inclination of the lamella traces according to (a) and (b). The complete set of stereographic projections for all colonies in (a) is provided as supporting information. For the pole projection of lattice planes, the normal vector of the planes is used. |
