Figure 4
The angular distances between lattice directions defined by four axes of HOLZ rings [schreibersite, (Fe,Ni)3P]. (a) The blue cross marks the pattern centre PC′ as initially derived using the Channel5 software (Oxford Instruments). (b) The dashed blue frame is used to calibrate the size of the Hilton net and consider the real position of PC′. The intersections of the lattice-plane traces (red lines) are used to define the correct positions of the wanted zone axes (corners of the black quadrangle). The Hilton net is aligned to enable measurement of the angle between two [uvw]i, yielding a value of ∼48°. |
