Figure 2
SEM images and inverse pole figure (IPF) maps for each crystal from EBSD. The colour coding shows the out-of-plane crystal orientation. The maps allow for different grains to be identified. For each crystal, the region surrounded by thick black lines corresponds to the grain orientation used for the computation of the orientation matrix. For some samples (i.e. 1F and 3A) only a small region on the IPF map corresponds to the grain measured at the synchrotron. EBSD samples the orientation of a cylindrical volume with a height up to 40 nm below the surface (Dingley, 2004). |
